This is a homework for MATLAB. Please answer using MATLAB functions and parameters. The answers are to be submitted as a .m script. Don't just list final answers. Search this paragraph to find other similar questions to answer please.

8 Answers are to be reported as pX= where X is the problem number. * For example the answer to problem i should be reported as pl- $ if it is a single part question, and pla= if it is a multipart $ question. This is how to report your answer for a single part question pl = sind (180); * This is how to report your answer for a multi-part question p2a = exp(-2*pi); p2b = fix (2*pi); p2c = mean (1:5); p2d = 'my answer is ...'; Problem 1: Use forward difference formula to estimate the derivative of the function f(x) = cos(x)esin (x) by performing the following tasks. (a) Create a vector x that has values from 7/2 to 7 /2 with a step of 7/100. Set pla=x. (b) Compute f and set plb=f. (c) Use function diff to estimate the derivative f'. Put the answer in plc. (d) What is maximum value of f? Put the answer in pld
