The equation

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

for

0 \le x \le 2\pi ,\;\,0 \le y \le 2\pi ,\;\,0 \le z\,\, \le \,\,2\pi

has

View answer and explanation

Correct option: A

One solution

Option A (One solution) is correct because the minimum value of sin(x) is -1, and the equation is only satisfied when sin(x) = sin(y) = sin(z) = -1.
