A Very Quick Question on the Formulae Booklet

Jippo · 2015-05-06 16:09:31

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.…

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.
