How can the right equation be converted into the answer on the left?
(sec^4x)(tan^2x)=(tan^2x + tan^4x)sec^2x

RS = tan^2x(1 + tan^2x)(sec^2x)
= tan^2x(sec^2x)(sec^2x) , because 1 + tan^2x = sec^2x
= tan^2x(sec^4x)
= LS

So I am suppose to evaulate this problem y=tan^4(2x) and I am confused. my friend did this : 3 tan ^4 (2x) d sec^ 2x (2x)= 6 tan ^4 (2x) d sec^2 (2x) She says it's right but what confuses me is she deriving the 4 and made it a three?
