Find R5 for f(x) = {eq}x^2 + 2x {/eq} on {eq}[0,10] {/eq}.
Question:
Find R5 for f(x) = {eq}x^2 + 2x {/eq} on {eq}[0,10] {/eq}.
Numerical Integration:
The definite integral of a function {eq}f(x) {/eq} over the interval {eq}[x_0,x_1] {/eq} can be approximated by a Riemann sum.
The interval is divided into subdomains {eq}[x_{n-1}, x_n] {/eq}
and the integral is approximated by the right Riemann sum
{eq}\displaystyle R = \sum_{n} f(x_{n})\Delta {/eq}
where {eq}\Delta {/eq} is the width of each subdomain.

{eq}x_0 =0 \\ x_1 = 10 \\ f(x) =x^2 + 2x {/eq}
The interval between {eq}[0,10] {/eq} is divided into 5 intervals of equal width ...
