Left Riemann numerical integration A curve is represented by column arrays xCoordinate and yCoordinate. Approximate the integral from xCoordinate(1) to xCoordinate(end) using the Left Riemann approximation method. Assign sumArea with the approximate area under the curve. Hint: A row array representing the area of each rectangle can be calculated by (difference between each element in xCoordinate)." yCoordinate(1end-1) f(x) f(%) 1. 3.5 and ycoordnate 12.4 7, then sumArea -(3-1X2)+ (6-3 Exr coordinate = [1, 3, 5] and yCoordinate = [2, 4, 7], then sum Area = (3-1)(2) + (5-3)(4-4 + 8-12.
