Question I've spent a lot of time working on this problem and i've gotten close but it never comes out right. Here's the question: 3cosX-cotX = (3-cscX)/secX
this is probably where you had the trouble. If so, here is a tip.
Sometimes you have to solve the left, right, or both sides. If one doesn't work, try the other, if the other doesn't work after you have tried that side, then try both, and if that doesn't work, either you did something wrong, need to change something, like cos(2x) can equal 3 different things and still mean the same, or you can only solve for x.
you would have to type in your problem like this 3cos(x) - cot(x), click enter on the keyboard, then try the other side like this (3 - csc(x))/sec(x)
and don't worry, it will understand cot(x), sec(x), and csc(x). also if you have square roots, you can right them like x^(1/2) or sqrt(x), but when graphing, don't forget you have a +sqrt(x) and a -sqrt(x), also with the +sqrt(x) you don't need the +, but with -sqrt(x) you do need the -, the graph won't do both sides, it only understands sqrt(x) as being positive.
