Having trouble graphing a non-linear graph

x = -2:0.1:2;

y = cos(x)+exp(-1/2*x.^2)*sin(6*x)

plot(x,y)

This is my code, I keep getting

Error in test (line 2) y = cos(x)+exp(-1/2*x.^2)*sin(6*x);

But I cant figure out what I am doing wrong.

Answer 1

x = -2:0.01:2;
y = cos(x)+exp(-1/2*x.^2).*sin(6*x);
plot(x,y)

Thank you!

[Neelanjan Pal]

when the code is as SUCH;

syms x y C
x = -2:0.01:2;
C=12/(cos(x)+exp(-1/2*x.^2).*sin(6*x));
plot(x,C)


error:
