# Math Help - Integration problem involving simpsons rule plz help

1. ## Integration problem involving simpsons rule plz help

Hi everyone,

i have got this question due for tomorrow if you know how to do it could you please tell me the answer and how you got it, please keep in mind i am only in high school so keep the working simple :

if you can help me ill appreciate it thx.

2. Simpson's Rule:

$\int_a^bf(x)\,dx$

$\approx\frac{b-a}{3n}\left[f(x_0)+4f(x_1)+2f(x_2)+4f(x_3)+2f(x_4)+\cdots+4f(x _{n-1})+f(x_n)\right],$

where $n$ is even.

You should use $[1,\,3]$ as your interval, with $n=4.$ To make things easier, you can bring the $\pi$ factor out of the integrand, and just use $[f(x)]^2$ in the above formula.

If you have any specific questions, then we can provide further help, but as this seems like a graded assignment you should not expect a full or detailed solution.

3. Can you or someone show me the working out it is only class work and goes towards nothing
