Find sinx, cosx, tanx, cotx, secx, cscx, without using a calculator. Each result should be a fraction. No decimals involved...

I dont even know where to begin, i missed a class, so please explain the work fully, Thanks kenny

**bobpursley**, Friday, July 31, 2009 at 8:55pmYou have some identity formulas...Look them up in your text...they go something like this:

sinTheta=sin(theta-n*360) and you could use that to find sin1110=sin30

There are others similar.
