Evaluating and plotting a kernel function

I'm trying to evalute the kernel function attached however unsure if I've input it correctly since not plot is showing.

% Evaluating kernal functions, kernal 2
n = 1:1:33600;
a = floor(n-(Fs/2)); 
c = (1200*pi)/Fs;     % c is greek letter chi
g = pi/Fs;            % g is greek symbol gamma

k2 = (sin(n*c)-10sin(9*n*c);    % ./
plot(n,k2)

% Evaluating kernal functions, kernal 2
Fs = 33600 ;
n = 1:1:Fs;
a = floor(n-(Fs/2)); 
c = (1200*pi)/Fs;     % c is greek letter chi
g = pi/Fs;            % g is greek symbol gamma
k2 = sin(n*c)-10*sin(9*n*c);   
plot(n,k2)
