I doubt it. Teachers don’t take an Hour to explain one concept, but they might take an hour working on examples to help you comprehend it. #respect for teachers
i feel like my teachers rely on basic examples to make you feel like it's easy and you can ace anything but then the tests come and they put a slightly hard question, we get tilted and we all feel dumb hope they explain thoroughly, not half-assed
i love this video ... i was really struggling to figure out how i was getting these trig equations wrong using the special triangles ... i wasn't using the reference angle!... i hope everyone confused about that Finds this video
thanks you so much for fixing what my teacher taught wrong. I was really confused doing this reference angle and looking at what my teacher did. Then i realized that she did the wrong way.
Hey, I have a pre calculus exam tommorow. If I don't make it, I want you to know that your videos helped me alot. Thank you. (edit: I somehow survived. W)
MR. Organic Chemistry Tutor, this is another classic topic in trigonometry that is easy to follow. Problem solving is the key to understanding this topic.
Guys. (Angle in degrees) mod 90. If its in quad 2 or 4 then take that result and get the compliment from 90. ie, -240deg mod 90 = 30, its in quad 2, so reference is 60. Way faster and easier to do in your head.
For 5:18, what if the given degree to me is -400 degree, Do I have to add it to 360 twice to make it positive or just once and remain it at negative state?
8:42 I think the reference angle for 3π/5 is 2π/5, like you show, but all your examples (except for this one) are only one π degree away from each other. So 8π/9 is only π/9 away from 9π/9. The example with 3π/5 is the only one where you have two "pi steps" away from 5π/5, because 3 is 2 away from 5. So π/5 is a reference angle also, but only as a reference guide... you would eventually count π/5 twice to go from 5π/5 to 3π/5, and that would equal 2π/5. All this to say... I think the π/x number is a guide, but not the actual reference angle. This video made me realize we need to be just a little bit careful when answering questions on exams if the denominator is slightly different than what we're used to, is that right?
The reference angle is in reference to the negative x-axis or the positive x-axis. In degrees it is either 180 or 0(same as 360). In radians, the negative x-axis is pi and the positive x-axis is 0(same as 2pi). It is too much work to convert to degrees then convert back again. For 8pi/9, it is just 8/9 of pi, which is 1/9 pi away from a full pi, putting it in the second quadrant.
H, at 01:27the question is the reference angle relating to the positive x axis, is that then the angle between the terminal ray and the positive x axis, so it will be 150degrees
গান শুনি তবে এই রকম গান,যেমনটি আপনি গাইলেন আমার মনের মত করে । আপনাকে ধন্যবাদ দিয়ে ছোট করার ইচ্ছা আমার নেই। আমার বিশেষ অনুরোধ রইল আপনার সান্নিধ্যে ,আপনি যেন আরও নজরুল সঙ্গীত পরিবেশন করেন। আমার ভাষায় বলতে হল মাশাল্লাহ।
If you draw a cartesian graph (Y axis and X axis), there are four quadrants, each separated by 90° 180°, 270°, and 360°, if you go around the graph from the positive x-axis, counterclockwise.
what abt when there's a large negative degree number like -680 and you have to find the reference angle? do you just use its coterminal angle between 90 degrees and 0 degrees?

Basically, the angle must be off the x axis and be between 0 and 90. I can't believe my teachers didn't even teach this

Cause we don't play attention in class🤣

dude. how do you make such easy to understand videos, its simply amazing
The entire video playlist is great! Organic Chem Tutor has some of the best math videos on RUclips.

His only example that confused me was when the reference angle was 2π/5.... I thought it would just be π/5

This helped a lot, but how do you know which quadrant the angle is in?

you lifesaver
what abt when there's a large negative degree number like -680 and you have to find the reference angle? do you just use its coterminal angle between 90 degrees and 0 degrees?
Thanks 👉😭👈
Thank u very much!!!
why cant we do 270 - theta if the angle happens to be in the third quadrant?
Very good
you’re so awesome
Thx It's helpful
thanks man!
Does this mean the reference angle of 35 is 35 degrees since Qreference=Q1 ?
Would it matter if there was sin, cos or tan at the front or would it all be the same
Thank you!
you saved me!!!
Thank you very much....
LOVE IT
4:59 (just putting a bookmark here when i come back from my 25 hour break bye)
I love you
you explained more in 1 min than i learned in 2 classes lol
Same
so much better than my teaxher
Trig test tomorrow and I gotta learn 5 weeks of material wish me luck
ty so much
I've learned the ways of the wizard in 12 minutes and 37 seconds
its hard when you cant listen to lectures in classes so you have to catch up on your own.
How about the reference number of -850?
The pain is temporary but the gain is… slightly less temporary 😅
Have a trig test next Tuesday
