Question

factor and simplify: cos^2x-sin^2xcos^2x ?

Answer 1

I think my first step is to take out a cos^2x so now it would be:
cos^2x(-sin^2x+1)?

Answer 2

Yes, \[\Large \cos^2x(1-\sin^2x)\]You should recognize what's inside the brackets.

Answer 3

so it'd be \[\cos ^{2} (\cos ^{2})\] ?
@agent0smith which would give me a final of cos^4x?

Answer 4

I think that's right.....

Answer 5

The medal was a hint :P
