–> Infinity

Raw Transcript

Hello Everyone, Tom from everystepcalculus.com and everystepphysics.com. I’m going to do another Limit to Infinity problem. Index 88 to my menu. Choose Limits. Scroll to compute limit. Enter the function by pressing alpha. This test problem is seven times x cubed plus nine. Uh oh, I forgot the left parentheses. Press second, go there quick. Divided by x squared plus 3. Add the Infinity indication. Choose the other button, and the yellow register is underneath. See the yellow letters, that’s what that does for us to that register when you press the yellow button there. I always show you what you’ve entered, you can change it if you want. which you better you can change it if want. You’re dividing everything, every term in that problem by the highest order term in the denominator. This here equals this and then we add infinity to these, it’s going to come seven because anytime you take a number. So when you multiply times Infinity it becomes Infinity. So here’s Infinity and second one is zero.Numerator Limit is Infinity. Denominator divided by the highest order term of denominator is this. That equals. When you’re add Infinity, that equals one zero. The Denominator limit is one. The Problem limit is Infinity then. Infinity over one. Pretty neat, huh? everystepcalculus.com, visit my site and buy my programs. Thank you

You are an angel sent from above TOM!!! Thank you so much for being patient with me. I got the programs to work and I am very confident I am going to pass this class once and for all. The Double and Triple Integrals programs are a life saver! Thank You Thank You Thank You!

Tom-    I showed my ex, who is a calculus professor, and he was waaaaaaay impressed. And he is an arrogant ass, who never helped me ever...I could tell he wanted to hate on it, but he couldnt.

Tom...I think that I’m finally done with Calculus II. In the prior test I got 78 and yesterday I finished all the problem on the test. I think I should be able to remain around the same grade. Thank you so much for your help; your programs really made the difference. They didn’t just solve the problems for you, in my case, they gave me the confidence and security I had lost with those stupid professors and the way they teach. To be honest, studying the programs on my calculator taught  me how to solve problems that I couldn’t do before due to the way they were presented. I felt confident and secure yesterday, and it only possible because either I remember  how to do the problems or the calculator would. Thanks one more time for time, dedication and quick responses. There is no other person in the whole world that would do what you do for us , college students being  killed  with freaking calculus classes.      John

Tom-     Got it to work with that link you sent me!  Just wanted to say thanks for all the great work you do, and for helping me pass this calculus class.  I'm going to tell everyone about this and make them pay the $30 dollars because you have done a splendid job programming my friend.  Let me know if you have any new programs for derivatives or integrals and Ill let you know if I need any more help!  Much thanks,                -Eric

I basically just needed to say that you're an amazing man. Basically saved my life during my emag theory course    

-DoubtingThomas  (Youtube vectors review here)

oh my god I figured it out. You're the freaking best!      -Sarah

Thanks Tom. I appreciate you taking the time to break down and explain these to me. :0)     -Nelson

 Tommy,     Great talking with you last night. I already liked you for developing this “most excellent program” but after our conversation I concluded you to be a great guy. I’ve been playing with this program most of the night, took in a few “z’s” and am back for more. This program really is superb. I did, however, notice that for some unknown reason when I attempt to do Relative Extrema’s and Trajectories that both programs came up as “Program not Found”. I’m not sure if I will be encountering the Trajectory stuff in this semester of Calculus but I do have a test this Thursday that includes Relative Extrema. Any suggestion, oh Master of this great creation?! I’m going to be gone most the day but should be home late afternoon if you got time to call. Same number (843-xxx-xxxx). That’s Myrtle Beach, 3 hours ahead of you and more golf courses than you can shake a stick at. Thanks    -Joe

Wow! Awesome! These are great, so great, thank you!            -Kristen

Tom is the man! His program is helping me pass my calculus class. He was willing to help me immediately when I couldn't get one of the programs working! This application is in my opinion a STEAL! I've never met Tom in person but I'll owe passing this class to every step calculus.
