## Main Question or Discussion Point

I'm not sure if this is the right place to ask..

Anyway.

Assume we have some integral I with 0 and 2 as limits. I = 3∫xe

Another unrelated question. In Euler's method for approximation, how do we choose our h value? The smaller the h is, the better the approximation, but is there a way to compute it from a given IVP?

^{x}dx from 0 to 2. What exactly do we have to do to find the partition points (and what are they?) but using the composite trapezoidal rule? I = 25.1671683 upon computing normally.Another unrelated question. In Euler's method for approximation, how do we choose our h value?
