A Texas Insturment emulator would be pretty cool. There are some pretty addicting calculator games out there for it.

Hey guys, when I try to use the Graphing calculator, it works. However, trying to use the viewing mode by fixing the xmin: -10; xmax: 10; ymin: -10; ymax: 10 seems to not really show 10 notches on each line, but still shows... 3 notches +y, 6 notches +x, 2 notches -y, 6 notches -x. How can I make it look like it has 10 notches all sides?

Also, after I graph the line, how can I find out y by selecting x=1? It won't let me type in 1 so I end up having to trace and ending up with all these decimal numbers.
On a t1-83, if i graph it and type 1 for x, it will show what y equals. I just want to know how to do that..
One more thing, after it's graphed.. and say I graphed it on mistake.. How can I get back to the graphing menu? Just like when I accidentally go to the matrix window, how can I get back to the main menu? or just simply go backwards to the window I was previously at?

THank you to whoever answers these questions

A few more questions, how do I simply graph y = (x)^3 - 9x ??
and how do I graph more than one line?

Thank you very much

Does this have the ability to do things like solve(), expand(), factor(), and the like?

Unzip it, and then if you are in 1.5FW, copy the content of the directory pspx48/fw1.5 on the psp/game directory of your memory stick.

That's all (all needed files are included in this zip file)

Yes, HP 48 is one of the best scientific calculator, even if it's an old one (1990).

Thank you very much

I suggest you to read the HP48 manual here : user guide

This calculator is powerfull but very hard to use

.

Anyway to enter in the plot menu, you must first use the green shift key (or R1 of your PSP) and then to 8 (plot menu), after you can edit your equation such as (x^3) - (9*x) and then draw it, zoom etc ...

I think xtiger would work incredibly well for the PSP since
you wont have to turn the psp 90 degrees to use it.

Oh yeah, i found the source code for it. =D
