I need help with integrals

Let f be the function given by f(x)=sin^2(x/4)e^(−x2). It is known that (top value= π/2)∫(bottom value=0) f(x) dx= 0.0223. If a midpoint Riemann sum with two intervals of equal length is used to approximate π/2∫0 f(x) dx, what is the absolute difference between the approximation and π/2∫0 f(x) dx ?
