The equation

\sin x+\sin y+\sin z=-3

for

0 \leq x \leq 2 \pi

0 \leq y \leq 2 \pi, 0 \leq z \leq 2 \pi

, has

View answer and explanation

Correct option: A

One solution

Option A (One solution) is correct because the maximum value of

\sin x

is 1, so for the sum to be -3, each term must be -1, leading to a unique solution.
