Use the power reducing_formulas to rewrite sin^2 3x cos^2 3x in terms of the first power of cosine.
Simplify your answer as much as possible.
Step by step solutions
1. sin^2 3x cos^2 3x = (1 - cos^2 3x) (cos^2 3x)
2. (1 - cos^2 3x) (cos^2 3x) = cos^4 3x - cos^6 3x
3. cos^4 3x - cos^6 3x = cos^4 3x (1 - cos^2 3x)
4. cos^4 3x (1 - cos^2 3x) = cos^4 3x - cos^6 3x
Answer: cos^4 3x - cos^6 3x
impatient much?
Once is enough, thank you.
