Limits and secants

[rogue846]

I dont clearly understand the limits or secants. Is there anyone who can explain them to me? I understand lim 0-> you put the zero in where x was and use it, but when it asks to 0 -> and follow it on a graph im lost.

I'm sorry, but we can't teach courses here. The topic of limits would require at least a week, and possibly a month, in a classroom setting, which we obviously cannot reproduce here in a short forum posting.

Please post the specific exercise with which you are having difficulty. Thank you.

Eliz.

Whereas I certainly agree with Ms Eliz that we cannot teach you a course online,
I will comment on this one.
If you have been lead(taught) to think that one uses substitution in finding limits,
you need to get your money back. Because that is totally wrong!
The idea is that if x→0, we are interested in values of x that are ‘near’ zero never equal to zero!
