Find the approximate area under the curve by dividing the intervals into n subintervals and then adding up the areas of the inscribed rectangles. The height of each rectangle may be found by evaluating the function for each value of x. Your instructor will assign you nj and /12. 2x v x- + 1 between x = () and x = 6 for nj and /2 Find the exact area under the curve using integration y = 2xvx2 + 1 between x = 0 and x = 6
