Webbsin 4 x = (sin 2 x) 2. Step 2: use the squared power reduction rule for sine. Step 3: substitute using . Step 4: Simplify. Although the formula for the fourth power could have … WebbSolution: We know that the formula for the definite integral of sin4x is given by, a ∫ b sin4x dx = (1/4) (cos 4a - cos 4b). Here, a = 0 and b = π/2. So, we have 0 ∫ π/2 sin4x dx = (1/4) (cos 4 (0) - cos 4 (π/2)) = (1/4) (cos 0 - cos2π) = (1/4) (1 - 1) = 0 Answer: 0 ∫ π/2 sin4x dx = 0 Integration of Sin 4x Questions FAQs on Integration of Sin 4x
