(a) find an approximation to the integral 2 (x2 − 4x) dx 0 using a riemann sum with right endpoints and n = 8. r8 =

Step-by-step explanation:

      n=8     f(x) = x² - 4x

convert [0,2] into 8 subintervals

width of each interval is

All subintervals are:

[0, 0.25], [0.25, 0.5], [0.5, 0.75], [0.75, 1], [1, 1.25], [1.25, 1.5], [1.5, 1.75] and [1.75, 2]

Let, be the right end point of each interval i=1,..8

Reiman sum is

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
