All you need to do is to use a simple substitution u = \sin (x), i.e. \frac {du} {dx} = \cos (x), or dx = du/\cos (x), which leads to Another way to integrate the function is to use the formula so

Integral of sin 3x sin x - YouTube

NettetIf u = cos x, then du = - sin x dx You don't have the - sin x, so you cannot make this substitution. Remember that in integrals, to use one of the standard forms, you need to have "du" which is the derivative of whatever you decide to call u.
