Helped me out a ton, not just with the hand but the whole lesson

Wow thank you so much for this!!! I've got a question, so do you only use the "All Students Take Calc" sign thing when you are dealing with reference angles??

hello there sir, question: in all cases when you are doing a somewhat more difficult problem, do you always just pay attention to the base? I know that probably doesn't make sense but I don't know how else to word it. um like for example if I had 3pi/4 (which I know is 135 and would be in the second quadrant ) could I just "graph, " for lack of a better word, pi/4 and get the same answer? or like if you had 7pi/6 just use pi/6, and 4pi/3 use pi/3? hopefully you understand my question, thanks. also this video was very helpful

I absolutely hate trigonometry, but this helps. Thanks !!!!
