Uh I'm new to calculus so if you could kind of walk me through it a little bit more that be great.

If you haven't learned differntiation rules then we will go with the quotient difference...ok the slope of a curve is given by ..so to get the devative of before you know differentiation rules is to go through this thus the derivative of is ...so the slope at the point x is ...so the slope of the curve of at x=2 is ...so the slope of the tangent line at the point x=2 has the same slope as the curve so its slope is 4

wow lol. and im only in chapter 2. i got 7 more chapters to go tonight and tomorrow.

- Apr 7th 2008, 04:36 PMMathstud28here let me make it a little easier

I'm a little confused though where you got those equations from. In my book they seem to be a little different. Damn I'm lost.

The 4th post in this thread

- Apr 7th 2008, 05:04 PMMathstud28If you mean
the limit stuff...hmm...thats something you just have to learn...here I think this will really help you its a great site..good luck! if you have any more questions just ask

Well what I mean is that it just appeared a little differently in my book. It's all good though.
