Error using cos Not enough input arguments. HELP

Hi all,

Can anyone help me with this problem - Error using cos Not enough input arguments.

cos^2(5*pi/6).*sin(7*pi/8)^2.+tan(pi/6*ln8)/sqrt(7)

#error

I'm new to MatLab and I need to plot a contour map using this function but I can't seem to find a way to get rid of the error message. Any help would be much appreciated.

Thanks, Mark.
