using char as formula inside a script

hi, i'm trying to use this character (as seen in the code) as a formula inside a script my main goal is to use this data and to place x=2 and to see the resault of the cos(2)

my code:

clear all close all clc

% integral solver

syms x
funct=sin(x);
answer=int(funct);
answer=char(answer);
x=2;
a=answer(1:length(answer))

Answer 1

What about just using subs (and you must mean -cos(2) not cos(2))

syms x
funct = sin(x);
intgl = int(funct)
finval = subs(intgl,x,2)

and then if you wish

char(finval)
