Help you do what? What is the statement of your problem? What does m have to do with it? We aren't mind readers.

Cot x= infiniti

As the limit approaches 0 from the right. Find delta that correspond to m=400

 

[LCKurtz]

Cot x= infiniti

As the limit approaches 0 from the right. Find delta that correspond to m=400

It isn't "the limit approaches 0 from the right". It is x that approaches zero from the right.

To start this problem, the first thing you need to do is state carefully what you are trying to prove. It starts like this:

Given M > 0 we must do what such that what...

State mathematically what you need to prove.

I only have to find values of delta that corrspond to m=400.

I only have to find values of delta that corrspond to m=400.

The point is that this means nothing without context- we have absolutely no idea what you are talking about.

However- wild guess- are you trying to find a delta such that [itex]0<x<\delta[/itex] implies [itex]\cot (x) > m[/itex] ?
