Homework Statement
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]
Homework Equations
Δx = [b-a] / n
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?
