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 WebCos3x gives the value of cosine trigonometric function for triple angle. The expansion of cos3x can be derived using the angle addition identity of cosine and it includes the term …
