hi bobbym

it looks like it's 1-e^(-x).

### Re: Oh,Oh,Oh,merry analysis!!!

so that would be it.btw i'm not looking for questions only about the big oh.they can be about little oh and theta as well.the omegas too.

could you also find the threads i posted about something connected to this stuff.i used little oh but you asked if i meant big oh.it was a problem i got from 'The Tangent".

see ya tomorrow!!!

You have done a little bit of it already.

How did you arrive at ln(x + 1)?

Hmmm. I see you like to prove things. Here is a question that is related in a distant way to what we are doing.

Prove there is a simple function that approximates the curve that the St. Louis Arch is.
