Use the formula + sin mh sin h + sin 2h + sin 3h + ... cos (h/2) – cos ((m + (1/2))h) 2 sin (h/2) to find the area under the curve y = sin x from x = 0 to x = 1/2 in two steps: a. Partition the interval [0, T/2] into n subintervals of equal length and calculate the corresponding upper sum U; then b. Find the limit of U as n →∞ and Ax (b – a)/n→0.
