Question

rewrite the equation 1 + cos x -2 sin^2 x = 0
in terms of cos x.

Answer 1

\(\sin^2 x + \cos^2 x = 1\)

Solve for \( \sin^2 x\) and substitute.

Answer 2

remember that :\[\sin ^{2} + \cos ^{2}=1\]

Answer 3

i dont know how to do that and want an actual answer

Answer 4

Can you solve the equation math gave you for sin^2
This equation sin^2(x)+cos^2(x)=1?
Can you get sin^2(x) by itself here?

Answer 5

how do we undo that addition of cos^2(x)
to obtain just sin^2(x) on one side by itself.
