Answer 1

No solution

Explanation:

You are given a function involving the sine of angle Ф instead of the angle Ф itself. Your task is to determine the angle Ф.

If 2 sin Ф - 3 = 0, then 2 sin Ф = 3, and sin Ф = 3/2 (or 1.5). Recall, however, that the value of the sine function is never less than -1 or greater than +1; therefore there is no solution.
