Is it possible to construct a code that for example we type in x^2 and then the program finds (d/dx)x^2=0 and gives x=0?
I have tried using syms x; diff(x^2) which gives 2*x but I don't know how to make it solve the equation. Perhaps I have to define a function handle? But f=@(x) diff(x^2) doesn't work.
Please help.
