Find the approximate area under the curve by dividing the intervals into n sub-intervals 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. n1 =6 and n2 =12

y=2xx2+1 between x=0 and x=6 for n1 and n2

Find the exact area under the curve using integration

y=2xx2+1 Between x=0 and x=6
