Question

sin^2(x)cos^2(x)-cos^2(x)

Answer 1

hard to tell exactly what you want done here, but i would start be factoring out a cos^2(x)

Answer 2

\[\cos^2\theta(\sin^2\theta-1)\]\[\cos^2\theta(-\cos^2\theta)=-\cos^4\theta\]?

Answer 3

What are you trying to do?

Answer 4

simplify

Answer 5

Yes that is correct.

Answer 6

Sin^2 + cos^2 = 1 Sin^2 - 1 = cos^2. Just had to use this on my calculus III test :(
