given x = 1,110 degrees
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

You 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.
