Matlab Only Outputting One Value

Hi, I am trying to evaluate the expression (cos(4*x) + sin(x))/(2*atan(2*x) + 2) for a list of x-values between 0:5. I go to solve but matlab only outputs one singular value. Also, when I try to plot it, nothing seems to come up. I'm sure the is definitely an error here with my thought process that maybe could do with some simplier explanations to help me understand. Does anyone know the reason for this and how to fix it?

code:

x = 0:1:5

x =

0 1 2 3 4 5

>> f = (sin(x)+cos(4*x))/((2*atan(2*x))+2)

f =

-2.401493151985125e-04

Use ./ instead of /
