Let’s examine your calculator a little further. There are actually six trig function keys on your calculator. The Sine, Cosine and Tangent keys – SIN, COS, TAN. There are also three more known as the inverse of Sine, the inverse of Cosine, and the Inverse of Tangent. SIN -1, COS -1 and TAN-1. Find these keys now. Where are they located?
