Question

How do you name an angle between `0^circ` and `360^circ` that is coterminal with the angle `-60^circ`?

Answer 1

`300^@`

Explanation:

If the result must have the same terminal side, we can simply add or subtract one full rotation (`360^@`) repeatedly.

`-60^@-360^@=-420^@`
`-60^@+360^@=300^@`
`-60^@+720^@=660^@`
The only result between `0^@` and `360^@` is `300^@`.
