I'm struggling with this one

[Benhij]

So I had a lesson with Simpson's rule 1/3 and I tried to solve this one but I got nothing , sorry I'm ask for too much and I'm really dumb I'm struggling with trig function to begin with , Can any one help ?

[MATH]\displaystyle \int \limits_a^b f(x) ~dx \approx \dfrac{b-a}{6} \left(f(a) + 4 f\left(\dfrac{a+b}{2}\right)+f(b)\right)[/MATH]
[MATH]a=0,~b = \dfrac{\pi}{3}\\ f(x) = \cos(x)[/MATH]
should be a pretty simple plug and chug. There should be an error bound formula somewhere in your text or notes. More plug and chug.
