The weights for a two-point open Newton-Cotes rule are the same as in a two-point closed Newton-Cotes rule (trapezoid rule). The quadrature points are x1 = a+1/3(b-a) and x2 =a+2/3(b-a). write a matlab function to implement a two point, open newton cotes rule, and use the function to evaluate a couple of integrals.

B3. Newton Cotes Method (student) [33 pts] 3) Use the Newton-Cotes formula f(x)-x) i-0 to estimate the integral -3x -1 with 5 evenly spaced grid points (compare to your reference value). (Hint: Use the method of undetermined coefficients to solve for the A, by substituting in f : i, x, x2, X3, X4 and demanding that the result of the integral be exact) Repeat with 7 and 9 points.

1. Please derive the formula of Simpson's rule. What is needed is a step-by-step derivation, with explanation why the next step can be taken. 2. Use the Midpoint Rule (see the book) and Simpson's Rule to compute the following integral: 1 + (cos x) dx Make a table of your calculation, in the form like this: No Value of Value of weight Value of function value of weight function Value of integral You are free to choose the value of...
Problem 2. In this problem, we will use Euler's formula to derive some trigonometric identities. (a) Using Euler's formula and the property that ez+w = e ew for any complex numbers z and | W, show that cost + sin? t = 1. (Hint: Start with 1 = eit-it.) (b) Similarly, show that cos(2t) = cos? t – sint. (Hint: Start with cos(2t) = Re(ezit).) (c) Similarly, show that sin(2t) = 2 sint cost. (d) Similary, show that cos(3t) =...
Problem 1 (1) Derive a basic quadrature rule RM(f) to approximate I= f(r)dr by integrating an interpolating polynomial po(r) of degree 0 that interpolates one data point generated by f (x) at the node (a+b)/2. (2) Give a geomet- ric interpretation of the rule and then derive the rule using the geometric interpretation.
