1. derivation and proving of simpson's rule using runge-kutta method

i need help in deriving and proving this numerical quadrature

thank you

Hey lmnsct.

You should show some attempt at the solving the problem yourself.

You will need to define how you estimate the derivative [as a result of your quadrature scheme] and then use that to estimate the integral.

Note - the integral is found by taking the initial condition and then adding derivative estimates across the interval of integration.
