Trying to make sure I have these correct for the following problems. Thank you for the help.

1. Limit [as x approaches 1] of: x^1/(1-x)

2. Limit [as t approaches 0] of: e^(qt - pt)/t

3. Limit [as t approaches pi (3.14)] of: sin(t)/ (t^2- pi^2) ------ pi = 3.14

4. Limit [as x approaches infinity] of: ln(ln(x))/ln(x)

Thank you again for your insight.

When finding the second derivative implicitly, I know that you take the derivative of the first derivative.....but I'm not sure how to do that implicitly.

For example:

x^2+y^2=4
2x+2yy'=0
y'(2y)=-2x
y'=(-2x)/(2y)

Now what do I do? I do know that the answer is -4/(y^3)...

What are they? How does one arrive at them? Why are they special? What is maximum likelihood? Is it related or something else entirely?

I could never figure this out. The one is used to model and describe relations in a triangle and the other is used to described periodic phenomena.

What is - briefly - the relation?

Most understandable answer wins.
