A function is given for a definite interval. Infact exact problem coding is not required.The solution must be general.
  1. f(x)=x^2;0<x<5
  2. f(x)=x;5<x<8
Now how to integrate this and plot this I came up with
syms x
then using heaviside function I could plot e.g c.*heaviside(t)-c.*heaviside(t-5);first part
But how do you convert the sym to matlab variable again
Help is higlhy appreciated
