MATLAB also has the cosd() function, so you can use cosd(30). Have a look at the trigonometry documentation for other similar function.

MatLab will do all calculations in radians as a default. So if you want to calculate
ans=cos(30);
in degrees you'll need to write:
ans=cos(30*pi/180);
ans=sqrt(3)/2
Otherwise, if you calculate
ans=cos(30);
in MatLab you'll get:
ans=0.1543
