What are you trying to show that it is equivalent to?
Can anyone show me how to do this problem?
This if how far I have gotten
I am not sure how to proceed unfortunately?
I have another trigonometric identities I need some help in although I do not want to start a new thread. It is similar.
cos^4x+2cos^2xsin^2x+sin^4x I need to simplify it this is what I have done thus far
cos^2x+2sin^2x+sin^4x factor out sin^2x
then I get this cos^2x+2+sin^2x But I do not think this is right?
