This Is Honestly The Sixth Try Not All On Here That I Have Tried To Get An Explanation That I Can Understand For

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 n1 and n2.
y = 2xx2 + 1 between x = 0 and x = 6 for niand n2
Find the exact area under the curve using integration y = 2x vx2 + 1
between x = 0 and x = 6
Explain the reason for the difference in your answers.Math
