1. The problem statement, all variables and given/known data Express the integral of (sinx + 1) dx over the interval [0,pi] with a Reimann Sum using 4 subintervals of equal width and letting x_i^* be the left endpoint of the subinterval [x_(i-1), x_i] 2. Relevant equations Δx = [b-a] / n 3. The attempt at a solution Δx = pi/4. The Reimann sum is (pi/4)Ʃ(1 + sin (pi/4)i) with i = 0 and the upper bound being N-1 or 3. Is this correct?
