I have the TI-89 but probably the same..
if I understand you question "idk" ???

set it up for split screen mode\f2\split screen
to toggle the apps 2nd\apps

hope this helps.

I meant i dont know (idk) what the parent function is, in terms of calculator syntax. for a logarithmic function it's log(x) i think, but what about an exponential function? isn't it y=a^x or something? what do i put it in the calc?

e^(i*pi)

I'd go with $y=e^x$

I've never heard of the "parent function" before. (Other than changing diapers. (Wink) ) So I Googled it and here is the list I got...
