- Опубликовано: 8 авг 2024
- MIT grad shows how to solve for the sides and angles of a right triangle using trig functions and how to find the missing sides of a right triangle with trigonometry basics. To skip ahead: 1) For HOW to CHOOSE A TRIG FUNCTION to solve for a side you don't know, skip to time 2:10. 2) For how to SOLVE for the LAST SIDE with TRIG, skip to time 6:18. 3) For how to SOLVE for the LAST SIDE with the PYTHAGOREAN THEOREM, skip to time 8:41. 4) For how to SOLVE FOR THE LAST ANGLE, skip to time 10:38. For my video that introduces the BASIC TRIG functions (sin, cos, tan, csc, sec, and cot) and SOH-CAH-TOA, jump to: • Basic Trigonometry: Si... Nancy formerly of MathBFF explains the steps.

HOW TO SOLVE A RIGHT TRIANGLE: If you have to "solve a right triangle," it just means to find all the missing angles and sides of a triangle. When you have a right triangle and you already know at least one of the angles (other than the right angle) and at least one of the sides, you can solve for the other sides using a trig function: sine, cosine, or tangent. When solving right triangles, you can use the memory trick sohcahtoa (SOH CAH TOA) to remember the trig ratios for sin, cos, and tan. Pick the trig function that includes both the side you already know AND the side you're looking for. You can use algebra to solve for the length of the unknown side, to find the missing side of a triangle. Once you have that side, you have two options for finding the last unknown side. You can either: 1) use another trig function, or 2) use the Pythagorean Theorem formula. Then you will have all the sides. Make sure you have found all the angles inside the triangle so that you've really "solved" the whole triangle. If you know two angles already (one of them is the right angle, 90 degrees), you can find the last unknown angles really quickly. Since all three angles have to add up to 180 degrees, you can subtract the two angles from 180 to find the unknown angle in degrees.
For how to identify adjacent, opposite, and hypotenuse sides of a triangle, and for an introduction to the trigonometric functions sin, cos, and tan, jump to my BASIC TRIGONOMETRY intro video: • Basic Trigonometry: Si...

@@elihamilton5842 yo id be careful telling people your school name on youtube, even if it is in the comments of an educational video.
The fact that she writes backwards on a clear board is amazing
she probably writes normally, then mirrors the video.
I think they just mirror the video if not I tried it out that it's not that hard to write
It’s a mirrored video
Omg that's true I feel bad
Yea it is tuff

Grow up.
Let me just say, THANK YOU! I have struggled with math for quite some time now, this year I am in geometry and I would try and try but could never even understand. This video and others on your channel made me understand! Thank you!
You are gery clear and concise. You do not talk too fast and explain every step. I WISH every math lecture on the planet was explained by you. Thank you so much.
I learned more in the first 6 minutes than with 5 hours with my physics teacher.
Gerald Irvin really? Y’all gotta speak up
What kind of Physics teacher is gonna spend time to teach you how to calculate basic trigonometry? 😂You mf tripping. I doubt it's the teachers issue when you expect physics teacher to explain you elementary school concepts
I learned more in this 10 minute video than I did in 2 weeks in my math class. THANK YOU!
Nancy, great video, explanation beautifully. now learning a lot more than b4.
thank you.
Hi
Same here.
SAME
How are you?
I have watched your channel since 8th grade, now I'm in the end of my sophomore year. It helps so much!! Thank you for the knowledge. I thought I would never understand a lot of things in math, but you've proven me wrong. Keep up the good work 👏 ❤
She also puts her beauty in the equation. That’s a smart thing to do
Thank you so much. This helped me so bad. I don’t usually comment on videos but I felt the need to on this one. I struggle with math a lot and so I use RUclips to help me all the time. A lot of the time, RUclips helps and I learn. But I don’t remember ever being this interested in math before and I don’t remember learning so much in such a short period of time! You don’t understand how grateful I am for this. You have gotten yourself a new subscriber and I am so pleased to have found you
Thanks for your help, I’m sure I’m not the only one who can agree
Try to learn with your own teacher guys I ask her all the time
it has help me a lot.thank a lot and send ur number

Wait ,do they teach you this at college?
I'm 71, writing a Win32 program to calculate and print a segmented vertical transition curve for a model railroad. (Readily available spiral formulas won't work because of the long rigid wheelbase of steam locos.) It's been 56 years since I did any trig. Although I recall a lot of the basics (esp SOH CAH TOA), I didn't recall the process of the actual calculations. This was a fast, clear, and precise refresher, and I'm back to programming. Thanks!

Ok, the thing that impressed me the most is that she wrote everything mirrored
no she mirrored the video XD smh
Thats too complicated. its a mirror video
Bruh 🤣
same.
she writes on a window normally(with her right hand) and then whilst editing the video she also mirrors the whole video which looks like she is writing backwards, tequnically it's am illusion.

That moment when you already know everything Nancy explains but you watch anyway.
That moment when you know you are supposed to pay attention but still cannot manage.
Or understand nothing..
i clicked even though i already learned this a few mins earlier

I know how to solve this 5 years ago but I'm still waiting 😍
Thank you so much Nancy, i haven't done trig in over 20years. Your explanation was so great that i was able to remember .💯
Thank you so much. I always struggle with math and this video was so helpful. You really helped me understand this WAY more than watching a whole lesson for like 35 minutes.
The teacher: Wow all the boys aced the exam
Girls: ITS SO HARD
The boys: paying more attention than usual.
Ha got it

Booooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
she smooth wit it
-Quote from Nancy
In 13 minutes you explained more than my teacher who took 2 weeks to explain it. I have a unit test tomorrow and this really helped! Thank you so much you explain this way better
This helped me so much thank you, I have been worrying about my math test all week and now I feel great
She Explains this so much easier than everyone else.
I’m really glad I found your channel. You have a nice mix of simple math to calculus. Great for a refresher on many types of math. Nothing I love more than numbers.
I got it! This was easier to follow than other RUclips videos. Me old school builder this will save much work and time, thank you Nancy.
This video helped me so much, I am honestly very grateful for you. You literally helped me get through lineman school. Thank you❤️
Excellent explanation! I also like the “speed up” and “speed down” sound and visual effect. Well done!
FACTS BRO
Damn all you simps I’m the comments 😂
You are? All of them? Why'd you let all the simps post?😉
@warner tesla they aren't, I think he trolling
I came here to understand more but i end up getting more distracted lol
@warner tesla no budge everyone who milks the word simp won’t understand
Lol
I was stuck for several hours with trying to understand this. You helped me understand within thirteen minutes. Thank you very much.
Thank you, so much. I did not have the option of having an instructor for my trig course. You are saving my life.
The way you pronounced "Pythagorean Theorem" and "emphasis for the syllables" got me laughing! Love it. This video was really helpful, thank you!
Nancy: it just means find all the missing sides and angles.
Me: That's EXACTLY what my teacher said, yet, here I am.
P.S Awesome video btw
Thank you so much. I have been looking everywhere on how to do this and I finally found answers. Since I am homeschooled I don’t find out how to do this during school but since you presented me with answers I can finally finish my work.
Man You are a life-savior! It was like I knew what to do but yk I just needed hint... thank you so much!
Thank you Nancy, I've spent hours trying to figure this out, going to tons of different videos but yours is the only one that explains it clearly, you probably just saved my grade.
I seriously LOVE that you explain things as if I have little to know background knowledge. Like your explanation of what makes something an opposite or adjacent side. It helps me so much in all your videos.
This actually one of the most helpful videos I’ve watched. Thank you
The most gorgeous mathematician of all times
NancyPi, your videos are extremely helpful. You helped me get through college algebra a while back and now you are helping me with calculus for engineers! Your magic X method for factoring quadratics has stuck with me and it has been a lifesaver. You are great at explaining math and i'd like to think you are somewhat responsible for my newly acquired love of math. Keep up the great videos, you are helping the world more than you know!!
I am japanese, and I love math.
I found this beautiful teacher a while ago. Your voice is so confortable.I will continue to listen to you carefully.
Carefully?
Sugoi!
Comfortable*
Nani?
No offence
Man... I should have found this video before my math exam. Literally explained every issue I had when solving trigonometry in general.
i like this because she explains in very quick and simple terms while also showing what she’s doing in a visual and easy way.
I could not remember how to do this to save my life, despite the fact I'm in a physics class and should really remember how to do this. Thanks for the refresher.
I've learnt this in secondary school 30+ years ago but never had to use it since, so have forgotten all about it. It's coming back with this video now.
Your explanations are exceptionally clear, thank you so much for these videos!
Thank you so much! I wanted to let you know your videos are still helping people LIKE ME. I was so confused and I was to shy to ask my teachers and you explained everything so well. I'm in 10th grade and it's got a little spice in it when it comes to difficulty of math and your videos help me remember why math can be fun.
Damn if this girl was my trig teacher no cap I would impresss her and actually learn

No, just fail her class and have to take it again, then get a 4.0, then impress her. That's the rule of thumb.
Excellent run down. As a builder years ago I taught myself Trig to do more tricks with fancy roof rafters etc. That took me a couple of weeks to do what you did in 14 minutes.
Istg I watch so many math vids but Nancy pi ALWAYS helps. Like fr she’s so clear and her videos help sm
POV: you’re not failing in math and is pretty gifted at math but your teacher doesn’t explain the why in SIN COS TAN and you want to understand it better.
Our teacher is somehow able to teach so fast and slow at the same time
I use your videos in my classroom often to supplement my own teaching. Thank you for doing what you do!
Wow! Your videos are awesome! The combination of camera trickery and your amazing talent of writing backwards really defines what a quality of maths video is! Keep up the good work!
Professor Nancy Pi, thank you for an outstanding video/lecture on Solving Right Triangles. This is an error free video/lecture on RUclips TV.
genuienly, you are the only person who can explain math to me properly. thank you so much truthfully, you explain it in MY WORDS
Thank you so much you are literally saving my exam grade!
Yeaniva Seisay facts
Well, I was away for a while and missed several videos. I spent the first half of this year as a full-time volunteer algebra tutor at a local "continuation" high school, for students who weren't well-served by the regular system. All had failed algebra at least once, and most had failed entire years of school. Many had severe life stresses outside of school, with family, poverty and various drug dependencies and mental health issues. A number of them had jobs, and many were on the verge of aging out of the system.
The first thing I learned is that, despite being a master of algebra, I didn't know a thing about teaching it. So, immersion in pedagogy was an initial task.
The second thing I learned was that being able to teach algebra wouldn't magically enable these students to learn it. Most weren't in a state of mind or heart that was conducive to learning anything, much less something as abstract as algebra. The vast majority believed they had no math abilities, and the rest believed algebra had no practical role in their lives.
With all this stacked against them, they then had to contend with the intense frustration and self-imposed humiliation they felt when they couldn't do a review problem they had been able to solve a year previously.
The third thing I learned was that I had to start with these students where they actually were, and not where I thought or hoped they would be. That meant asking if they had slept the night before. Had eaten breakfast. Weren't too hot or cold. Felt well. Were hydrated. Weren't (too) high.
The fourth thing I learned was that to find out where they were I had to become a powerful observer, a gentle questioner, a rock-solid presence for them, and find ways to create a space of safety and careful risk-taking.
I had to do lots of work on myself. To learn to get close to students without going over the edge. To "love them to death" as one teacher put it to me, without killing myself. To be totally warm and open, yet keep a safe distance.
I didn't have nearly enough successes, but damn if I didn't have some awesome ones! I remember one young woman who would do this low "Ohhhh" when she "got" something, and I remember watching her take a test where she did that twice, during the test!
There was a very sullen young man who was always high (and a genuine ass of the first order), but who somehow agreed to come in straight enough to give algebra a serious try. He couldn't do any of the review problems, so I grabbed the prior text and went through it backwards. We got to the point where we found his problem was multiplication: He had forgotten how it worked, and had never memorized any multiplication tables. We started from there and made slow but steady progress. One day walking across the quad between classes, I saw him on the far side: He changed direction to come past me for a fist-bump. Two of his other teachers were also there and were shocked, nearly to the point of tears (as was I). It was the first time any of us had seen him have a positive self-directed interaction with any adult on campus!
There were more victories like that, large and small.
Then my savings started to run low, and I had to get another day job as a senior systems engineer. It's a great job, with a talented team working on cool products. But I find I'm in a bizarre state: I've never had a job I liked more and loved less.
Because my heart isn't in it: What I want to do is teach! So I'm living on a fraction of my salary, saving money for tuition for my teaching credential, saving money to pay off my mortgage, and saving money so I can afford to live on teacher's pay in Southern California.
To tell you the truth, the students who "get it" I'll turn over to you: They won't need me for much, and you've got that ASMR thing going. I want to work with students who think they have an allergy to math combined with existential dread and nightmares.
Beautiful experience. You are right, the first thing to tackle is their fear of math. When we get to high school we are told "you're going to see algebra uuuh" as if it were a demon. And then in university it is "calculus oooh so difficult". But we all have a brain capable of math. I blame said fear and the people that don't know how to teach, who just make students feel worse. Congratulations.
Number Line Nomad and the Duchess of Denominators have profound respect for your sincere dedication. Have a MatheMagical year!
good job.
