Evaluate the Riemann sum for (x) = x3 − 6x, for 0 ≤ x ≤ 3 with six subintervals, taking the sample points, xi, to be the right endpoint of each interval. Give three decimal places in your answer.

Step-by-step explanation:

Given that ,

Interval length = 3-0 =3

No of intervals= 6

Hence the end points are

Right end points are

x  0.511.522.53total

f(x)  -2.875-5-5.625-40.6259-7.875

Integral value  0.5*(-7.875)-3.9375      

So Riemann sum is -3.9375

= -3.938

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
