If you try to get the airy equation or:
desolve(y''xy=0,y) for example, you'll get a solution that has G_1 and G_0 in the answer. Are these intended to indicate "some constant"? Thanks in advance Donald

They are the arbitrary constants that occur when solving the ODE.

Thanks Parisse.....that's what I thought, but wasn't sure.
Thx Donald

They are not G0, G1 and so on since those are the reserve graphic object variables. G0 specifically is the live screen buffer.
TW Although I work for the HP calculator group, the views and opinions I post here are my own.

I'm coming to the party a little late on this one, but my resources all use c, or c1, or c2, etc., for the arbitrary constant. G_0 is visually confusing compared to what I normally encounter. Did you feel that G_0, was less likely to already be used than c, which might have already been used in a program, for example? Here is an example: (simplify set to 'none') Code: desolve((y') = (x*y/(x^2+1)),y) result: (G_0*x^2+G_0)/(sqrt(x^2+1)) Simplifying makes it a little clearer, but G0 versus c, makes it less so, (to me, anyway). Code: simplify(desolve((y') = (x*y/(x^2+1)),y))
