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 $$\frac{2c}{4*\pi}$$
