Integrate sinx sin3x

We recall the double angle formulae and rearrange it for sin 2 x. We recall the Pythagorean identity and rearrange it for cos 2 x. We substitute the cos 2 x expression into the double angle formulae. We then group the sin 2 x terms on the LHS and simplify to give the above expression. As you can see, the LHS is looking more like our integration problem except that the angle we require is 2x. To get 2x we use a little trick as shown below.
