Nettet21. des. 2024 · The cos2(2x) term is another trigonometric integral with an even power, requiring the power--reducing formula again. The cos3(2x) term is a cosine function with an odd power, requiring a substitution as done before. We integrate each in turn below. ∫cos(2x) dx = 1 2sin(2x) + C. ∫cos2(2x) dx = ∫1 + cos(4x) 2 dx = 1 2 (x + 1 4sin(4x)) + C.
