Question

Find the values of the six trigonometric functions of an angle in standard position if the point with coordinates (5,-12) lies on its terminal side.

Answer 1

Using A^2+B^2=C^2

12^2+5^2=169

Hypotenuse= 13

Sin(Ø)= 5/13

Cos(Ø)= 12/13

Tan(Ø)= 5/12

csc(Ø)=13/5

sec(Ø)=13/12

cot(Ø)=12/5
