Question

What is 1/e eqivalent to?

Answer 1

It's e^(-1) but I don't think that's the answer you are seeking.

As a series, see attachment.

Answer 2

Yes, directrix, it's not what I'm looking for... but thanks for trying :)

Answer 3

e is approximately 2.73.... its a transcendental number like pi

so e^(-1) = 1/2.73...

Answer 4

oops thats e^1

Answer 5

For what are you looking about 1/e?

Answer 6

I'm seeing if it equals 0, so that it can pass through the origin.
Eg..
y=1/e passes through the origin..

Answer 7

We are not talking y = 1/(e^x). Correct.

Answer 8

no.... its never zero.... because you graph e^x

negative powers mean 1/e^x.... the only way the graph goes below the x-axis is for an equation such as

y = e^x - b where b is a constant

Answer 9

pick up a calculator... it has a function for e

Answer 10

yes, but when I do 1/e, it gives syntax error.

Answer 11

enter 1/e1

Answer 12

Oh. Ok. 0.3679 it's giving me.

Answer 13

that 1/e^1

then 1/e2 will be smaller
1/e0 = 1

Answer 14

yes, it's true

Answer 15

hope that helps

Answer 16

Have you seen this http://www.wolframalpha.com/input/?i=y%3D1%2Fe#

Answer 17

if you have a graphing program of calculator... graph y = e^x and then y = e^(-x)

Answer 18

Oh, that helps @FoolForMath
I don't have a graphing program... except wolfram

Answer 19

just enter graph y = e^x etc

Answer 20

@order: Apart from wolframalpha, Mathematica, Geogebra and Grapeq are good choices.

Answer 21

Thanks! :-)

Answer 22

Glad to help :)
