This looks messy, but we do now have something that looks like the result of the chain rule: the function 1 − x2 has been substituted into −(1/2)(1 − x) √ x ...

On the other hand, we know that R n(x) goes to 0 as nincreases. So the idea is to make j R R n(x)dxjsmall by increasing n: In our case, we want to nd nsuch that j R 1=3 0 R n(x)dxj

  Example Express sin3 x cos4 x as a sum of constant multiples of sin x. Hence, or otherwise, find the integral of sin3 x cos4 x. Solution.Sincecos2 x =1 sin2 x, cos6 x =(cos2 x)4 =(1 sin2 x)2 =1 2sin2 x +sin4 x. So, sin3 x cos6 x =sin3 1 2sin2 x +sin4 x =sin3 x 2sin5 x +sin7 x. For the sake of simplicity, we will denote
