I got to this, but I get an error :
f=2.*x.*sin(6.*pi.*x+exp(2.*x.*cos(6.*pi.*x.)));

f=2.*x.*sin(6.*pi.*x+exp(2.*x.*cos(6.*pi.*x.)));
%^ remove this dot
Correct is
f=2.*x.*sin(6.*pi.*x+exp(2.*x.*cos(6.*pi.*x)));

syms x
%vv close vv remove dot
f(x)=2.*x.*sin(6.*pi.*x)+exp(2.*x.*cos(6.*pi.*x))
f(x) =
