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 Webb30 mars 2024 · Ex 7.3, 10 Integrate the function 𝑠𝑖𝑛4 𝑥 ∫1 sin^4⁡𝑥 𝑑𝑥 =∫1 (sin^2⁡𝑥 )^2 𝑑𝑥 =∫1 ((1 − cos⁡2𝑥)/2)^2 𝑑𝑥 =1/4 ∫1 (1−cos⁡2𝑥 )^2 𝑑𝑥 We know that 𝑐𝑜𝑠⁡2𝜃=1−2 〖𝑠𝑖𝑛〗^2⁡𝜃 2 〖𝑠𝑖𝑛〗^2⁡𝜃=1−𝑐𝑜𝑠⁡2𝜃 〖𝑠𝑖𝑛〗^2⁡𝜃=(1 − …
