Hi!

jeff> expand will do all sorts of things, including making partial
fractions.  also, if you're ever

that, try messing around by
jeff> expanding them and factoring them or vice versa.  sometimes it makes
it collapse it more.  very
jeff> strange.

so far i haven't used factor(), i (sad but true) dont know what does
it do. i've got my TI for 2 weeks only... so i have much to learn


jeff> now, differential equations.  does anyone know how to make the 89
solve differential equations
jeff> with greater than second derivative?  y''', etc.  it will take y' and
y'', but gives argument
jeff> error if you type y'''.  is there another format, or does it just not
support it at all?

try Differantial equation solvers - DiffEq
http://www.paxm.org/symbulator/download/diffeq.zip

i'm sure you will be satisfied ;-)
