Trigonometric Equation Solver

Solve simple trigonometric equations of the form sin(x) = value, cos(x) = value, or tan(x) = value. Solutions are provided in degrees within the primary interval.

Solution Notes:

- sin(x) = a → x = arcsin(a) and x = 180° - arcsin(a)
- cos(x) = a → x = arccos(a) and x = 360° - arccos(a)
- tan(x) = a → x = arctan(a) and x + 180° for other solution

All angles are given in degrees within 0°–360° for sin/cos and 0°–180° for tan.

Ensure the input value is within the function’s valid range: sin/cos [-1,1], tan (all real numbers).
