You're missing a close-paren. Is your original expression meant to be either of the following?I need to rewrite (sin(2x)^2 in terms of cos(x)
(sin(2x))^2 = A(cos(x)^4+B(cos(x))^3+C(cos(x))^2+D(cos(x))+E
and find A,B,C,D,E=?
You're missing a close-paren. Is your original expression meant to be either of the following?
. . . . .\(\displaystyle \Big(\sin(2x)\Big)^2\)
. . . . .\(\displaystyle \sin\Big((2x)^2\Big)\)
When you reply, please include a clear listing of your thoughts and efforts so far. Thank you!
You may not be able to discern all of the steps to the final form, just by looking. But that doesn't mean you can't try stuff.It is the first one.
. . . . .\(\displaystyle \Big(\sin(2x)\Big)^2\)
I really have no idea how to solve it that the reason why I am asking here.

\(\displaystyle \text{Write }[\sin(2x)]^2\text{ in terms of }\cos(x).\)
