Use the squared identities to simplify 2sin^2 x cos^2 x a. (1+4cos(2x)-cos(4x))/4 b. (1+4cos(2x)+cos(4x))/4 c. (1+cos(4x))/4 d. (1-cos(4x))/4

The given question is

Multiplying and divide by 2

Again multiplying and dividing by 2

And

So we will get

Correct option is D

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
