Question

Give an expression that generates all angles coterminal with the given angle. Let n represent any integer. -210°

Answer 1

For any integer n, we can say that θ and θ + n(360°) are coterminal angles. So, the general expression:

$-210+n\cdot360=-210+360n$

provides all the angles which are coterminal with -210°.

Answer:

$-210+360n$
