Trigonometric Functions of Any Angle - Unit Circle, Radians, Degrees, Coterminal & Reference Angles
This trigonometry video tutorial explains how to evaluate trigonometric functions of any angle such as acute angles or special angles. It shows you how to find and use reference angles and coterminal angles to accomplish such a task as well as converting between radians and degrees as needed. This video contains plenty of examples and practice problems.

how do we get the 11,60,61? at 4:50 please show me the solutions for it
I love how he explain things so casually in like 3 sentences, easy to understand while my teacher needs to explain a simple concept in 1 hour, 20 minutes per example.

I really didn't understood trigonometry in my high school. And now I'm studying calculus in university. Thanks to this guy, I have understood everything in an hour that I couldn't understand in 6 years .
For those looking for unit circle and radians that begins at 28:00

love your pfp
You have no idea how much time you’re saving me from relearning everything even if my professor had just explained it. My finals are coming up but he teaches it in a way where there is no explanation given just examples. I love the way you teach and explain I have been watching your videos a lot more should have started earlier though.
What a great review to watch!! I'm making so much "neuro-connections" to trig than ever before... Thank You, The Organic Chemistry Tutor.
Having exams in the morning and you just saved me. Thanks
U just relieved me from overthinking about the formula SOHCAHTOA, thank u so much
I'm taking uni calc right now and highschool was almost a decade ago so the lectures I've gone to so far have felt like gibberish to me but I feel like your channel is going to be super helpful so thank you so so much! ! You are amazing! You really are a god send! Love your channel so much!

Oh my god, because of the way he explains everything in trigonometry I get what my teacher is saying. Thanks a lot
Before I watched this video, I was so confused on how to solve these problems with the unit circle and triangles, but this video goes step by step easily😊! Could you please make another video on how to solve problems that cannot be easily found with reference angles, the unit circle, etc.?
Professor Organic Chemistry Tutor, thank you for an excellent video/lecture on Trigonometric Functions of Any Angle- Unit Circle, Radians, Degrees, Coterminal and Reference Angles. Learning Trigonometry starts with these classical Transcendental Functions and how they relate to the Unit Circle. Thanks to the viewers for finding and correcting the error(s) in this video.
since then i attended this for the first time, i love watching this always and it is helful.
it should be [-2sqrt(13)]/13 and not [-2sqrt(13)]/3. Small mistake.

thank you sooo much men i hope you will get your donations someday your dah best
these vids are perfect Brodie, TYSM
Thank you sir we really appreciate your work
thanks bro very useful video i appreciat it
think of the quadrants as CAST where Q1 is A=all, Q2 is S=sin , Q3 is T=tan and Q4 is C=cos. This helps me remember.
Gg love everything but 14:02 it should be over 13 ✌🏾

3 weeks with 3 days and 2 hr long lectures and only needed a 1 hr video to actually understand. Good lord teachers should just play this video for one lecture and that's it, save everyone time.
I love you explain carefully
Thank you!
Great vid.
I use a more friendly one by saying 9:50 All Students Take Cab So All-first quadrant (all is positive) Student- second quadrant (sine is positive) Take- third quadrant (tan is positive) Cab-fourth quadrant (cos is positive)
*THANK YOU*
You might as well write your own textbook too because your examples always seem better than my book.
life saver!
Thanks!
Thank you very much, I now I understand what to do for my upcoming exam!

What if I only have one side as a given? I encountered this in a activity yesterday.The given was tan = square root of 5 ( that makes it the opp, am I right? ). Using TOA is it alright if I assume that the adj is 1 ( if I assume it as [square root of 5/1] )?

32:39 While this video is older I don't see the reason to do this round about way to get to the answer, doing 180/9 = 20, so then you can do 5 * 20 * 9/9, then 5 * 20 = 100, same amount of math but a less painful way imo
13:58 the right answer is -2√(13)/13 not -2√(13)/3 it's just a small human mistake

Can someone help me please? I have a question. At 13:55 he says "-2(root13)/3" Where does the 3 come from?
I. LOVE. YOU
how about if sin theta is = 2/5 and theta is in quadrant II.. find csc theta and tan theta.. help please..
ily
51:10 sin is root 3 / 2 and cos is 1 / 2, tan is sin/cos. So the answer is - root 3

If the radical is at the top, it mustn't be rationalized?
