In what form should the answers to trigonometric equations be given?
The question usually indicates the form of the answer.
e.g. If the domain is given as 0 ≤ x ≤ 2π then the answer should be given in radians, in terms of π if practical.
If the domain is given as 0 ≤ x ≤ 360° then the answer should be given in degrees.
