Differentiation interpretation help!Hey! It's been a while! Hope you are all good! #2 20121108 09:03:15
Re: Differentiation interpretation help!Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121108 09:13:52

Re: Differentiation interpretation help!Hi The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #6 20121108 23:53:03
Re: Differentiation interpretation help!Ok can we please start simply? #7 20121109 00:22:37
Re: Differentiation interpretation help!hi Karimazer1 The deltas are used in place of 'd' to show that one variable is being treated as a constant while differentiation is applied to the other. On a 3D graph, the result is as if you had cut through the surface with a plane parallel to one of the x axes. To come back to your question, which variable are you differentiating with respect to ?

Re: Differentiation interpretation help!Hi bob thank you. I mean #9 20121109 04:23:27
