1. ### The number e as a limit

Ok thanks it worked
2. ### The number e as a limit

I'm sorry if it takes time to respond, I have like several question to answer at the same and I must give this tomorrow lol Don't worry, I keep track of what I write on paper. I'll respond here if something I'm having a problem with.
3. ### The number e as a limit

Wait, what I just wrote was correct or not ? Am I in the right direction ?
4. ### The number e as a limit

OK but I'll have to take the natural logarithm right ?
5. ### The number e as a limit

1. Homework Statement I have lim of n > infinity (1+1/n)^n 2. Homework Equations 3. The Attempt at a Solution I know that I must use l'hospital rule and setting ln y = n ln (1+1/n) And after lim n ln (1+1/n) as n approaches infinity. After what do I do ?
6. ### Simple circle problem involving area and circumference

You obtian the radius. Btw why are you desesperate lol
7. ### Simple circle problem involving area and circumference

c=2*$\pi$*r
8. ### Simple circle problem involving area and circumference

How ? I don't know what there is to do next.
9. ### Simple circle problem involving area and circumference

Ok, I need to go now. I'll answer you when I get time. I'm very sorry :/
10. ### Simple circle problem involving area and circumference

It's asking me specifically to use limiting process. It's a kind of introduction to calculus problem, that's why. So I can't use the technique you showed me :/
11. ### Simple circle problem involving area and circumference

Yeah, but Im finding my derivatives with limits because it's what's asked in the problem. And it's derivative of what to time ? Area ?
12. ### Simple circle problem involving area and circumference

I don't understand the question. I will get the rate of change of the the area depending of the time we're talking about.
13. ### Simple circle problem involving area and circumference

Yeah, that's what it is.
14. ### Simple circle problem involving area and circumference

Yeah sorry about that : $$\frac{c}{2*\pi}$$
15. ### Simple circle problem involving area and circumference

Ok, so I evaluated the quotient and it gave me $$\frac{2c}{4*\pi}$$
