    Very simple question folks ye might be able to help me with.

    Could one of ye go into the Maths Tables and see is the anti-derivative of cos^2(x)=(cos x)^2 in there?

    I know that I can rewrite (cos x)^2=(1+cos 2x)/2 and work from there if necessary but wondering is

    "Integral of cos^2 x = (1/2) (x+(1/2) sin 2x )"

    in there.

    Thank you for your help.

    EDIT: I found that the answer is yes.
