WebbHow to reduce power of trigonometric identities? To reduce the power of squared trig identities, follow the below steps: Example: Find the value of sin2θ, cos2θ, and tan2θ, if the given angle is 30 degree. Solution: Step 1: Write down the angle. Θ = 30 Step 2: Place the angle value in the trig functions given above to calculate the value. 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
