Okay, since it seems reasonable to hang the trig functions off of PMCs,
we'd best get a list of the functions we want. I can think of:
pow
logarithm
square root (yes, I know, it's for speed)
Normal and hyperbolic versions of:
sine
cosine
tangent
cotangent
arcsine
arccosine
arctangent
arccotangent
There are, I'm sure, others. The base version of these, which all classes
will share unless overridden, will just get the double value of the PMC in
question and perform the operation on that, so we only have to do this
once by default, but classes can override it if they really, really want
to.
