Answer:

sin(x)cos(x) = -4/9

Explanation:

Square the given equation, and solve for the desired product.

(sin(x) +cos(x))^2 = (1/3)^2

sin(x)^2 +2sin(x)cos(x) +cos(x)^2 = 1/9

1 + 2sin(x)cos(x) = 1/9 . . . use the trig identity for sin²+cos²

2sin(x)cos(x) = -8/9 . . . . . subtract 1

sin(x)cos(x) = -4/9 . . . . . . divide by 2
