Integral of sin 3 cos 2

Nettet28. jan. 2024 · Then, with simple substitution, I got ∫ ( sin 3 θ) d θ = 1 / 3 cos 3 θ − cos θ + C. When I plug in my end points π / 2 and − π / 2, I get zero. However, it can't be zero because it's a legit solid piece. So, I tried to solve with wolphram alpha for sin 3 θ and my integrand before simplification, I got followings: I also found this ... 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.
