Determine a region A whose area is equal to lim_{n\rightarrow\infty}\sum_{i=1}^{n}\frac{\pi}{4n}sin(\frac{(i+n)\pi}{4n})
(i)under the graph of f(x)= sinx from x=0 to x = π 4
(ii) under the graph of f(x)=\frac{1}{4} sinx from x=0 to x=\frac{\pi}{4}
(iii) under the graph of f(x)= sinx from x=\frac{\pi}{4} to x=\frac{\pi}{2}
