How to I find a limit coming from either the left or right on a TI-89? I know how to use the limit command, but that doesnt specify a left or right approach.

Hello !

In general, if you don't know the syntax for something, go to CATALOG and find the command. At the bottom, you should have some kind of short example.

For the limit, it is

Code:`EXPR,VAR,POINT[,DIRECTION]`

In your case (ok, I knew it lol, the beginning of my post was for general questions), it's, for example :

Code:`limit(1/x,x,0,1)`

limit(1/x,x,0,1)

> $\displaystyle \infty$

limit(1/x,x,0,-1524654778797)

> $\displaystyle -\infty$

Got it ? :)
