Sin 135o = Sin ( 180o - 135o) = Sin 45o. Cos 310o = Cos (360o - 310o) = Cos 50o. Sin 210o = Sin (210o - 180o) = - Sin 30o (Sin is negative in third quad) Cos 112o = Cos (180o - 112o) = - Cos 68o (Cos is negative in 2nd quad) The Four Other Trig Functions. The following are the defintions of the other 4 trig functions. tangent of : tan = y/x
