Show Work Step by Step on your TI-89 Calculator Screen

Hello again, everyone. Tom from everystepcalculus.com and everystepphysics.com A limits at infinity problem. Index eight to get to my menu. You’re going to scroll or get to limits. Choose that. You’re going to choose limit to infinity. You’re going to enter the function by pressing alpha first. You have to do that in every one of my programs. And this is a test from calculus one. One divided by parentheses X minus to infinity. I’ll show you what you’ve entered, you can change it if you want I say it’s okay. We’re dividing it by the greatest power in the denominator. In this case is X. One is the numerator. So one over X is equal to one over X. And when you substitute infinity for X, it becomes zero. Denominator is X over X or three over X equals one or three over X. And 0 divided one, the answer is zero. These are all simple if you really know the trick. If you don’t they can be trouble.
