Question

How do you find the trigonometric functions of values that are greater than `360^@`?

Answer 1

Since the values of trig functions remain the same if you add or subtract a multiple of `360^circ` to or from the angle; for example,

`sin(390^circ)=sin(390^circ-360^circ)=sin(30^circ)=1/2`

`cos(-630^circ)=cos(-630^circ+2cdot360^circ)=cos(90^circ)=0`.
