Question

-sin squared theta over tan squared theta

Answer 1

is cos squared theta

Answer 2

sin^4 theta -cos^4 theta over sin squared theta -cos squared theta?

Answer 3

simplify it

Answer 4

sin\[[(\sin x)^4 - (\cos x)^4] / [(\sin x)^2 - (\cos x)^2] = (\sin x)^2 + (\cos x)^2\]

Answer 5

simplify cos squared theta -sin squared theta cos squared theta
