I'm 31 years old now and going back to get my diploma(which we call dogwood here in Canada). Your videos have helped me immensely, the teachers that I have and text books aren't clear enough but you certainly make it clear. I really appreciate that you made this, thank you from the bottom of the heart.
short, to the point, helpful, and easy to understand. I have a test today due at midnight and my teacher is incompetent. thank you for teaching me this in 12 minutes what he couldn't in 4 classes
These videos have helped me to help my son, who sits his GCSE exams starting tomorrow. Thanks so much for such a great way of teaching all of these subjects. There really is no reason for parents to shy away from helping their kids with such great help and the manner in which you teach these really does aid learning.
@@AwesomeSauceyperson Sorry for disturbing you but could you explain why sin35 equals 0.57, tan48 = 1.11, and . Do sine, cosine, and tangent have values? Also, what is the need for sin^-1?
@@neelrama5938 it’s because you want to find what sin(35°) is so you need a calculator to find that If you use your calculator and say sin(35°) it will tell you it’s 0.57 and the same goes for tan(48°) it’s 1,11 There is a button for sin, cos, tan Yes sin, cos, tan have a value Sin^-1 is used for finding angle degree just like the first one you asked about sin(35°), tan(48°) etc I hope this helps you to give a better understanding of trigonometry :-)
idk if this helps anyone but here's some quick definitions of stuff: theta - angle opposite - the opposite end of the angle adjacent - beside the angle hypotenuse - what makes the triange a triangle (longest side) some better stuff to lower confusion: arcsin/sin -1 ---they both mean the same thing just laid out differently (same goes with cos and tan)
Love it! I'm in school right now and they just dropped a sneaky little trig class out of nowhere, I'm sweating bullets, this is a great video, I wouldn't mind seeing more of these just for repetition, all the other videos from others just confuse me, well done to you sir
I got excited at the "friendly equation" to the side, I had no idea other people did that! got me through loads of chemistry, glad you're spreading the word about it:)
After completing this video I agree that trigonometry is one of the most feared topics in mathematics. I learned that trigonometry only works on right angled triangles. I learned that the length of the sides are named (a, b, c) due to its respectively opposite angle. I memorized the 3 equations as SOHCAHTOA. Allow me to demonstrate it: Sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse and tangent equals opposite over adjacent. Sine= SIN, Cosine = Cos and Tangent = Tan.. As I was watching this video the lesson became easier and easier. You are already provided with 1 angle which is 90 degrees and more information will be given to complete it. All you have to do is place the numbers in the right place according to the equations and simplify them to get your results. Your final answers may turn out in decimal numbers. Don't freak out, just continue and don't overthink it. If your teacher allows the use of calculators, you will be able to do it on it. However, only use the calculator to make sure of your answers or if huge numbers are given. I honestly thought I would have numerous questions to ask. However, I watched various videos before this one. The way you explained it was phenomenal. Great Job!!!!!
memorizing SOHCAHTOA isnt a really good way of understanding the sin, cos and tan functions. I'll give you a better more geometric interpretation of these functions. So, if you take any point A, on the unit circle, (circle with a radius of a unit, in the cartesian plane)draw a line to that point and the origin, (0,0), and draw a perpendicular to the X axis, and then join that point on the axis back to the origin, you get a right angled triangle. The line you just drew to the X axis is the sine function! Isn't that cool? The math is pretty simple, since sin = opp/hypt, the hypt will always be 1 as its the radius of the original circle so it will always be just the opposite side. Similarly, the compliment function to the sine, aka cosine or cos is the line you drew from the point on the x axis and the origin. Same math. The tangent function is the point you get by drawing a *tangent* to that unit circle at that point A (yes, thats where the tan function gets its name). The segment you get by taking the distance to that tangent segment and the X axis gives you the tan function, and the segment you get by joining the tangent to the Y axis gives you the compliment of that tan function, aka cotangent or the cot function. So just by using pythagoras' theorem you can derive the ratios on the spot, without ever needing to memorize it
Also, if youre interested in calculating any value of sin(x) without knowing the opposite or the hypotenuse, there is a very beautiful series, called the taylor series. According to this series, the value of sin(x) = (x^1/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) and so on forever. Truncate at any point, and you get a veryy good approximation of sin(x). This is also btw what calculators use to compute the value. similarly, cos(x) is the same as sin of x, except it has every other even number, instead of the odd number pattern of sin(x) If you dont believe ill solve an example out by computing the sine of 1 as i said sin(x) = (x^1/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) so therefore sin(1) = (1^1/1!) - (1^3/3!) + (1^5/5!) - (1^7/7!) + (1^9/9!) (and i chose one cause powers of 1 are easy to compute) sin(1) = 1/1 - 1/6 + 1/120 - 1/5040 + 1/326880 sin(1) = 1 - 0.16667 + 0.00833 - 0.00019 + 0.000003 = 0.83333 + 0.008311 + 0.000003 = 0.841664 which is a very good approximation of sin(1). (actual value being ~0.8414)
Even though I knew this already I really appreciate the great videos. Also I love that I wasn't the only one who wrote simpler equations to get the order right!

Tip for slow learners like me - set playback speed to 0.75 - it still sounds quite normal, but just gives a bit extra brain processing time!
for 6:00 . For 0.57 = x/12 i would say that 12 is multiplied by 0.57 because its going to the other side of the equal so it will be inverse as 12 was originally dividing with x but when it is put to the other side of the = sign it becomes multiply. Likewise for the other symbols + become - etc 👍

Thank you very much. I'm a 25 year old guy and I needed to know how to find an angle's number for a personal project. I've studied these things when I was in high school but never understood them until today.
I like this video but it seems trigonometry is ultimately 'How to use your calculator.' Any chance of a run through without a calculator including all basics needed to work it out the old fashioned way? Cheers.
Hi, you seem to understand what he was going on about with 3=6/2. Would you be so kind as to explain in an idiot proof way how this relates to the sum?
I've just just started trigonometry in maths and after 1 hour of my teacher trying to explain it to me and not understanding it , your method made me understand it all , thank you so much
Thank you. Clear and friendly. Voice tone is so important; sometimes videos have super scientific and rushed narratives. Your friendly voice helped me to concentrate on the facts.
This was so clear and helpful. My only request is that it would be nice to see what the equation would look like in the calculator when using the inverse of sin cos or tan. Like 0.71 cos^-1

My son needed help with trig for schoolwork. This is helping me learn it faster than any other math channel. Thank you!
I will be patron soon. I need to learn curves and more today.
This video is simply INCREDIBLE, thank you!!
Thanks so much for posting this.
Trying to help my son with his exams, but it's been 40 years since I did trig and it hasn't been easy remembering it, but thanks to this video I am at one with it again.
Thanks . I always remembered soh can toa but never knew how to apply it to a right side triangle. I guess I missed that class when my teacher showed it. Anyway I am now 48 years old and came across your video
How simple. I can't beleive not one teacher couldn't see i was struggling with this and could not explain it like you just did.
Thank you
Soh cah* toa. Although I'm going to assume that's autocorrect's doing
@@TLPH04 lol yes the beautiful auto correct. Thanks
love this vid was really struggling because i couldnt understand the way my teacher was teaching me and this really helped.
Mate I'm 40 ans about to start an engineering degree at UNISA and can tell going to be watching alot of your videos, keep up the good work you are a good instructor especially for Aussies, no offence to the Indians but you're heaps easier to listen to
how's the degree going?
4 years later and this video is still saving lives, thank you.
If a person did not use a calculator, what is the formula from cos to get the degree of the angle?
If x is your cosine value, the angle is approximatly (180*(π/2 - x - x³/6 - 3x⁵/40 - 15x⁷/336))/π degrees
@@HakanTheUltimateHoca In other words, good luck not using your calculator
Wow this absolutely saved me in my geometry class
I'm doing mechanical engineering just started never thought it would be so heavy with maths
Engineering seems like something that would require quite a lot of math
Is it not more physics based than maths
@@Anonymous_56789 it's both and they put them in long confusing questions
This makes sm sense thanks I finally understand trig
SO HELPFUL!!
EXCELLENT REFRESHER, I NEEDED THIS THANK YOU SO MUCH!!!
Yo calm down it’s just math lol
Thanks for the help
Thank you very much. I'm a 25 year old guy and I needed to know how to find an angle's number for a personal project.
I've studied these things when I was in high school but never understood them until today.
Silly old harry Caught a haddock Trawling off Australia. That’s what we were told
I was told silly old Hitler couldn't advance his troops over Africa 😂
@@tom-ez1np This Hitler one is easier to remember, but I don't like giving props for Hitler.
When trying to become a pilot trigonometry is #1. This video definitely helped me get a better grasp
I like this video but it seems trigonometry is ultimately 'How to use your calculator.' Any chance of a run through without a calculator including all basics needed to work it out the old fashioned way? Cheers.
same thought! it would be great without the use of a calculator, to get a better understanding.
Thank you! The video title didn't lie.
i hope you get 100 lottery tickets and win all of them
Thanks for that. My teacher explained it to me in a confusing way but I was able to go to this video and understand it in under 15 minutes.
W to all those who dident listen in class and decided to just search it up
Pov im in grade 11th and have 20/100 grade in math 10c
Wow that 3=6/2 formula is a life saver!! What brilliant method. Thank you!!
Hi, you seem to understand what he was going on about with 3=6/2. Would you be so kind as to explain in an idiot proof way how this relates to the sum?
I put 12*0.57 in on my calculator it didn’t say 6.88 it said 6.84 6:05
I've just just started trigonometry in maths and after 1 hour of my teacher trying to explain it to me and not understanding it , your method made me understand it all , thank you so much
He made a mistake. The cos -1 (.71) = 44.77 degrees not 45.1 degrees
Thank you. Clear and friendly. Voice tone is so important; sometimes videos have super scientific and rushed narratives. Your friendly voice helped me to concentrate on the facts.
This was so clear and helpful. My only request is that it would be nice to see what the equation would look like in the calculator when using the inverse of sin cos or tan. Like 0.71 cos^-1
Yeah, on my calculator it came up as 45.1 degrees only when I put in cos(-1) 0.705 not 0.71. How would you know when to round and when not to round?
