Symbolic input forms 49G+
Message #1 Posted by Helge Gabert on 25 June 2004, 1:24 p.m.

Does anyone know what happened to the input forms for integration,differentiation, Taylor polynomials, variable isolation, and solving quadratic equations on the 49G+? On the 48GX, they come up with R Shft Symbolic.

Not that I care much, since all this (and much more) can be done with the help of the CAS right on the stack. But is there some way to get at these forms (e.g., hidden menus?) on the 49G+ that I missed?

I'm only curious, as input forms did get carried over for the numerical solver. Thanks.

You either press AND hold the right shift
OR you released it
before pressing [ 7 ] NUM.SLV.
Try them both

I thought I made myself clear. But it appears I did't.

If you have a 48 GX: Press R Shft Symbolics (9).

See the menu that comes up?

[integration,differentiation, Taylor polynomials, variable isolation, and solving quadratic equations ].

Select one.

See the input screen(s) that comes up?

OK. This is what I don't get on the 49G+.

On the 49G+, when you press R Shft NUM.SLV, you get input screens for solving equation, differential equations, etc.

These have been ported over from the 48GX (I am aware of that). They are accessible under R Shft Solve (7) on the 48GX, as I have already mentioned in my first posting.

So my question remains: What happened to the symbolic input forms on the 49G+? Were they deleted from ROM?

It got lost in the port to the HP49G. See this thread:

Thanks for having confirmed this. I suspected they might have disappeared.
