My Text Book asked me to solve this problem using only the definition of the derivative. I found the correct answer using the definition of the derivative and then I wanted to test the product rule and the power rule to see if it would yield the same answer. To my frustration, I am getting a differe...

Thank you so much. It appears that I am starting to "get" it, but I also need to be more thorough in these proofs; I'll work on that.

Nona, thank you so much. Today I looked at that link http://www.purplemath.com/modules/inductn2.htm, which was in fact more explanatory than anything I could find, and wrote out the proof they were doing on my notepad. This helped and I realized something which I think was doing incorrectly that had...

I have a textbook and have researched several websites and have found numerous examples of induction to proving statements are always true, but no examples where induction proves a statement false (except where n=1 (or the base case) is false). Can induction even prove a statement is false (when the...

Hi, Can anyone help me understand where I am misunderstanding the principles of induction? I am trying to understand induction by using it to prove a statement is false (below) but I am not "getting it". Here is the principle of Mathematical Induction (from http://www.math.toronto.edu/oz/t...
