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.

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.
