Use the power reducing formulas to rewrite cos*2x in terms of the first power of cosine.
Simplify your answer as much as possible.
To indicate your answer, first choose one of the four forms below.
Then fill in the blanks with the appropriate numbers.
os*2x = ] - Ocos[]x + [cos]x
O cos]x
cos*2x = ] + Ocos]x + [cos]x
cos*2x = ]- Dcos]x
cos*2x = || + cos x
