How to get the simplified integral after using "piecewise"?

Good morning,

I wrote a code by using "piecewise" function , but after that when I tried to get the result of any integration , I got the result as a function of piecewise

How to delete this " getting the result without piecewise" ?

Thanks alot

% Code

clc

clear all;

syms x w n

int((sin(x))*sin(x*n),x)

ans =

piecewise(n == 1, x/2 - sin(2*x)/4, n == -1, sin(2*x)/4 - x/2, ~n in {-1, 1}, sin(x*(n - 1))/(2*n - 2) - sin(x*(n + 1))/(2*n + 2))

The answer:

int((sin(x))*sin(n*x),x,0,w,'IgnoreSpecialCases',true)
