Generally it is used for solving a single unknown in a single
equation. You can also write something like 'FUNC(X,Y)=X^2+Y' and hit
the DEF key (2) to define a little function solver that takes stack
input. When you define a function to graph, one is automatically
created for you. How handy!

There is one additional solver in the 50 not in the 48s. This is the
MSLV command which is a non-linear series numerical solver. Takes a
lot of inputs though and is kind of slow. Worked great at number
crunching for my statics/dynamics though. Then I discovered matrices
and could solve everything in one go. :-)

They lifted several chapters directly out of it for the 49/50AUR.
Just remember the CAS only likes to be in radians, and a plain number
without a dot '5 vs 5.' is a symbolic integer and you'll be fine.

I don't remember correctly if the equations library solver on the 48
solved units as well. . .
