MATLAB plotting question.

Hi, I am trying to plot out this function y(t) = A cos(xt + s(t)), where A = 1, x = 2 and s(t) = -2sin(t) over 0 to 40 sec in increments of 0.05 sec. I am using this code:

t = 0:0.05:40;
y = cos(2*t - 2sin(t));
plot(t,y)

However I keep getting an error unexpected MATLAB expression. Can anyone tell me what's wrong. I am new to this. Thanks!

"2sin(t)" should read "2*sin(t)"
