Simplify Command

	After seeing some of the questions in the news group I have one about
the Simplify command.  It doesn't seem to know DeMoivre's theorem.  For example
in trying to work with Spherical Harmonics you often want the Sin and Cos
combinations of a +/- pair but you cannot get this without typing it in.
Perhaps one reason for this is that a negative exponent is written as the
1/Exp[m] form and Simplify doesn't understand this.  Is there anything to
do to correct or overcome this problem?
	I have a second question about the Notebook font size.  I would like to
change it but dont know the file.  I have looked in 3.0 book and in the 2.2
Front End manual but neither seems to mention it.
	Thanks for your help.
