Hi all,
I have searched the forum and have been having a hard time finding something in regard to what "e" represents. I followed a link from here to the Mathisfun.com site (http://www.mathsisfun.com/numbers/e-eulers-number.html), and I feel that I understand how to obtain e as a number. A very good explanation. One shortcoming on my part, is I still do not understand what exactly its purpose is.
I have read that it is a constant, and at P(0,1) on an XY graph, the slope is equal to y at that point exactly. All functions of x that are negative result in an extremely low Y coordinate, until reaching positive values of x, where a change in Y dramatically increases positive. I am just not understanding what (1,e) represents on that same graph.
I am studying calculus materials in my spare time, and have read of this important number, and want to understand it better. Any help would be very much appreciated!

Thank you Jane, Mathsyperson, and Daniel for your responses. That one was just bugging me. I got that wrong on a test a couple semesters ago, and as I looked over notes, I wanted to know the answer to that one, and how to find it. I didn't ask this of the instructor at that time, so thanks once again everyone !

Yes, Mathysperson, you are correct ! My mistake, and thank you for pointing that out. So now I have:
If
then
And if
then
Is my solution set for x :
and
?#81 Re: Help Me ! » So stuck » 2008-08-10 06:24:35
Then, is it:
then plug it into the quadratic formula?

Thank you JaneFairfax, but I am still having trouble. I do understand how you got to this point. I am usually not having problems of this magnitude with my fundamental skills, but I still can't seem to pick it up from here, either. Please continue to be patient with me... 
Am I on the right track ?

Well I am just plain stuck on this equation, I need to find x and I just can't do it. So I am turning to all of you instead.
What is the solution for x ?
Thanks in advance !

Yeah, not that scary at all, actually. I am a babe in the woods compared to all of you regarding math, but thanks for the welcomes regardless.

Hi,
I would have my name for username, but it was taken. My loving wife calls me Chewy, and so do many of my friends. Long story, maybe I will share it some day ...
Anyway, I LOVE math ! I am currently in college, and had a great time in College Algebra. I am looking forward to my classes this fall, and I like learning about math whenever possible. I must admit, when I first started coming to this forum before registering, I felt a bit intimidated. You all seem so extrememely bright ! My fascination has led me back here over and over.
But I decided to join when Jane helped out a person with a question, and she was very kind and helpful, and I felt that I should join, because I really do feel that math is fun, and I want to learn.
I look forward to reading more. Have a great day all !
Chewy (real name Eric, by the way). "Chewy" works fine though.
