# Solve Limit arctg (x) - Get Help Now

• Jalo
In summary, the conversation is about someone asking for help with solving a limit problem. They are not familiar with l'Hopital's rule and are looking for alternative methods to solve the problem, such as using inequalities involving arctan. Others suggest using the arctan function or treating it as a difference quotient to solve the problem.

## Homework Statement

I need help solving this limit. If anyone coud«ld help i'd be grateful

## The Attempt at a Solution

I have no idea how to solve the indetermination...

Did you try l'Hopital's rule?

This is a problem for calculus 1, I'm not familiarized with l'Hospital's rule :\

Do you have any inequalities concerning arctan you can use? Something like 0<=arctan(u)<=u for u=>0?

All I've been given was the limit above. I'm supposed to know what's his limit when x tends to zero

You have know something about the arctan function to solve it. Can you solve it with the inequality I gave you in the last post? BTW I was sloppy and wrote it incorrectly. I fixed it.
