2. Let f (x) = sin x. a. Plot y = f (x) on the interval [0, 7 ] in the space provided. Include the rectangles produced using Right-Hand Riemann Sums with n =3 to approximate the area under f on the interval |0, 7 ALANI atla 2 IT 3 JT 5 JT w/y NIX 3 4 b. Approximate the area under fon the interval 10 , 2 by writing out the terms of the sum obtained using Right-Hand Riemann Sums with n = 3 and then adding the terms for the result. (Report exact-value results and a four-decimal-place approximation.) c. Use technology to approximate the area under f on the interval | 0, using Right-Hand Riemann Sums with n =100. (Report a four-decimal-place approximation.)
