I would like to answer the following question from the MATLAB book by holly moore

11.21

and

11.24

so for the 11.21 problem, I have already solved it. The thing is I’m only trying to get rid of the sym function since it’s a paid tweak.

I would like you to replace ‘sym’ function with the f(x)=@ function [If you need any more clarification about this matter lmk].

for 11.24

I would like to answer it from scratch as I couldn’t answer it myself.

please provide the answers in .m script file.
