your fun is neither acceppting nor using inputs
You should write the symbolic function like this
fun = @(x)cos(x);
x0 = fzero(fun,0.5);

I do not understand what tangent lines through the origin for cosx has to do with xsinx ? Tangent lines to cosx would have to do with sinx not xsinx .

Create a function file and save it to the same dierctory as
function y = f(x)
y = cos(x);
end
Then use this function in the section of your script as
%%
fun = @f; % function
x0 = 0.5; % initial point
ff = fzero(fun,x0);
