Vectorize the midpoint rule for integration The midpoint rule for approximating an integral can be expressed as ∫badxf(x)≈h∑i=1nf(a−12h+ih), where h=b−an. Write a function midpointint( f, a,b, n ) to compute the midpoint rule using the numpy sum function. Please be careful in generating i, which should range from 1 to n inclusive. (You could, for instance, use a range and convert it to an array.) Your submission should include a function midpointint( f, a,b, n ).
