Question

use the riemann sum definition of the definite integral to show that 3*(integral from b to a) x^2 dx= b^3-a^3, here, for simplicity, we assume b>a>0. be sure to clearly specify your mesh/grid xi, dx, and your choice of smaple points xi

Answer 1

ok so how do you get the riemann sum?

Answer 2

are u there?

Answer 3

i send u a message.

Answer 4

Yeah, I know~ it was just a question to see where you were with this

Answer 5

but I'm not quite sure what this mesh/grid thing is
