Question

How do you determine the measure of an angle coterminal with the angle -3 radians?

Answer 1

`theta=-3+2pi*n,n\in ZZ`

Explanation:

Coterminal angles differ by integer multiples of `2pi` (measured in radians). All angles coterminal to `-3` radians can be written in the form:

`theta=-3+2pi*n,n\in ZZ`

where `n in ZZ` means "n is an element of the integers."
