Trig Tutorial

We simply take the inverse sine of both sides. On the left hand side, the sine and inverse sine undo each other and we are left with θ by itself. In order to plug this into your calculator, you need to use the 2nd function of the sine function. You should get an answer of 41.8°. Cosine and tangent have similar inverse functions, cos-1 and tan-1. ................
