In this video I go over another example on trigonometry integrals and solve for the integral of the integral of sin(4x)cos(5x). In solving this integral I make use the of trig product identities which I covered in my earlier video (see video link below in the related videos).

I don't always solve trig integrals but when I do the integrand is usually in the form of sin(mx)cos(nx) ;)
