Question: Using Python or Matlab: For the function f = cos(4x). (1) Plot graph of the exact solution (2) Plot graph of its interpolation. Use n

Using Python or Matlab:

For the function f = cos(4x).

(1) Plot graph of the exact solution
(2) Plot graph of its interpolation. Use n = 8 (8 subintervals). T=5.  

(3) Plot graph of its L2 projection. Use n = 8 (8 subintervals).
 

Use the Trapezoidal Rule and the Simpsons Rule.

 

Graphs must look like this.
