Find the exact values of cos((3pi)/4 rad) * and * sin((3pi)/4 rad) (1 point) (sqrt(2))/2 * (- (sqrt(2))/2); - 1/2 * (sqrt(3))/2; - (sqrt(2))/2 * (sqrt(2))/2; - (sqrt(3))/2, 1/2
The exact values of cos((3pi)/4) and sin((3pi)/4) are:
cos((3pi)/4) = -sqrt(2)/2
sin((3pi)/4) = sqrt(2)/2
Therefore, the product of cos((3pi)/4) and sin((3pi)/4) is:
(-sqrt(2)/2) * (sqrt(2)/2) = -2/4 = -1/2
So the exact values of cos((3pi)/4) * sin((3pi)/4) is -1/2.
