##### Calculus: 1001 Practice Problems For Dummies (+ Free Online Practice)
A limit problem asks you to determine what the y value of a function is zeroing in on as the x value approaches a particular number. You can solve a limit problem with your calculator using the arrow-number.

First, store a number into x that’s extremely close to the arrow-number, enter the limit expression in the home screen, and hit enter. If you get a result really close to a round number, that’s your answer—you’re done. If you have any doubt about the answer, just store another number into x that’s even closer to the arrow-number, get back to the limit expression, and hit enter again. This will likely give you a result even closer to the same round number—that’s it; you’ve got it.

This method can be the quickest, but it often doesn’t give you a good feel for how the y values zero in on the result. To get a better picture of this process, you can store three or four numbers into x (one after another), each a bit closer to the arrow-number, and look at the sequence of results.
