WebSolution: To find the integral of cos4x cos3x, we will use the formula cos A cos B = (1/2) [cos (A + B) + cos (A - B)]. Here A = 4x and B = 3x. So, we have cos4x cos3x = (1/2) [cos (4x + 3x) + cos (4x - 3x)] = (1/2) [cos 7x + cos x]. So, the required integral is given by, ∫ cos4x cos3x dx = ∫ (1/2) [cos 7x + cos x] dx WebWe can simplify it further to cos ( 3 x). Indeed, ( cos x + i sin x) 3 = ( e i x) 3 = e 3 i x = cos 3 x + i sin 3 x and the result follows by comparing the real component of the left and right …
