Best ResponseYou've already chosen the best response.1then skip it it takes a bit of explaining to know why \[1+\cot^2(x)=\csc^2(x)\] and even then if you do not know that cosecent is the reciprocal of sine, then it will still not make sense

Best ResponseYou've already chosen the best response.0well, here are some important rule: Sin^2(x)+Cos^2(x)=1 1/sin(x)=csc(x)... I forgot a lot XD.

Best ResponseYou've already chosen the best response.1if it was me, and i did not want to spend the several hours ( probably a few weeks) learning this stuff, i would do this http://www.wolframalpha.com/input/?i=1%2F%281%2Bcot%5E2%28x%29%29

Best ResponseYou've already chosen the best response.1if you really know nothing about this, then you either have to learn it, or you can't do it if you don't know the basic stuff about sine and cosine, none of this is going to make any sense at all, besides the obvious fact that you can't do something you know nothing about
