I have integral:

Int(-1;1) x^4 dx

Need to solve it using numerical integration.
Q(f) = A1(f(a)) + A2(f(x1)) + A3 (f(b))

A1 -?
A2 -?
A3 -?
x1- ?

Soulve integral and find error. Need to solve without programming (just on paper).
I am a little bit confused in solving this. Probably Simpson formula can be used, but not sure... My result has too big error.

n must be even for Simpson's rule. I suspect you are supposed to use the trapezoidal rule here...but that's a guess based on the format and what is being asked.
