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

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

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