Question
Find all solutions if 0 ≤ x < 2𝜋. Use exact values only. (Enter your answers as a comma-separated list.)cos 2x cos x − sin 2x sin x = 22x =
Solution
It seems like there's a mistake in your question. The equation "cos 2x cos x − sin 2x sin x = 22x" is not correct. The left side of the equation simplifies to cos(2x + x) = cos(3x) using the cosine of sum identity. However, the right side of the equation "22x" doesn't make sense in this context.
Please provide the correct equation so I can help you solve it.
