Use the method of upper sums to approximate the area under t

Use the method of upper sums to approximate the area under the curve f(x) = squareroot x from x = 0 to x = 4 for 4, 8 and 16 rectangles. Compare your answer to the actual area integral_0^4 squareroot x dx

Solution

if you have calulated area under the curve by method of upper sums for 4,8,16 rectangles, then compare the area for each of such reactangles with answer you have solved above.

You need to calculate the difference between the exact area and the area when method of upper sum is used.

Try to solve it and complete it, in case you feel any problem let me know I will be glad to help you out.

Thanks
