It is possible that you do not have the appropriate toolbox installed.

Run the command ver on the command line, and check whether the Symbolic Toolbox is one of the installed toolboxes.

You can go in your Matlab installation path and click to uninstall the program. When it asks you to select, select modify and then in the installation page, you can select any toolbox you have not installed yet to be installed.

You can use just :

syms x;

like this:

clc
clear
syms x;
f=(sin(x)^2)+log(x)+sqrt(x-1);
disp(subs(f,x,5));`
