WebTo solve the integral ∫ sin 2x sin 5x dx, we will use the sin a sin b formula. Step 1: We know that sin a sin b = (1/2) [cos (a - b) - cos (a + b)] Identify a and b in the given expression. Here a = 2x, b = 5x. Using the above formula, we have Step 2: Substitute the values of a and b in the formula and solve the integral.
