MATLAB QUESTIONS:

1) Code a function that uses the composite trapezoidal rule that can numerically integrate the function. Use it to solve the equation with 9 points.

2) Now do the same but use a function that uses the composite Simpson's 1/3 rule.

I need the following parameters in the functions:

I - the integral estimate

n - number of points for integration

x1,x2 - the limits of integration

fxn - function that requires integration
