Recall derivative function ratio rule g(x)=f(x)/h(x) ⇒ g'(x)=[f '(x)*h(x)-f(x)*h'(x)]/h²(x) In our case f(x)=sinx ⇒ f '(x)=cosx h(x)=x² ⇒ h'(x)=2x hence

Thus, sin(x)cos(x)=sin(2x)/2. intsin(x)cos(x)dx=intsin(2x)/2dx=1/2intsin(2x)dx From here, let u=2x so that du=2dx. =1/4intsinunderbrace((2x))_u overbrace((2)dx)^(du)=1/4intsin(u)du=-1/4cos(u)+C= color(blue)(-1/4cos(2x)+C You can also show that this is equivalent to the other two answers using the identity cos(2x)=cos^2(x)-sin^2(x).
