Program Troubleshooting

For a product rule problem, after I type the function. It says argument must be a string (error)? How do I fix it?

Go to “Product rule” in my menu and enter the two functions in this way: ( )*( )

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

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.
