The equation given is a sum of three products of trigonometric functions. To simplify it, we can use the identity sin(a + b) = sin(a)cos(b) + cos(a)sin(b). Applying this identity to each term on the left-hand side gives: Cos(x)Sin(y)+Cos(y)Sin(z)+Cos(z)Sin(x)=0 This equation is true when x, y, and z are all equal to pi/2.
