Question

Let µ be an angle in standard position that contains the point with co-
ordinates (-5;-12) on its terminal side. Determine the values of the six trigono-
metric functions of angle µ.

Answer 1

Draw the triangle. The horizontal length is -5, altitude is -12, and you do the calculating, hypotenuse is 13

Cosine Angle= -5/13 and so forth.
