(MATLAB) The following question needs to be programmed using MATLAB.

I need help in questions 1 and 2b only.

Formula (8)

I did provide Formula (8) earlier as well. I asked this question previously but the code was not correct. Although the formula is given for integral from -1 to 1, this is the only Formula (8) in the textbook for this chapter section.

1. Write a program to evaluate an integral Ja f(x) dx using Formula (8) 2. Continuation) By use of the same program, compute ap proximate values of the integrals cos X dx
