A. show
sin^2x cos^2x = (1 - cos 4x) / 8
by filling in the table below. start with the left-hand side.
b. find all solutions to the equation
sin^2cos^2x=(2-(sqrt2))/16

a. Recall the double angle identities:

Then

Applying the identity again, we have

as required.

b. Using the result from part (a),

(where is any integer)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
