## Homework Statement

Find the slope of the tangent line to the curve y=x

^{3}at point (-1,-1)

(i) Using Definition 1

m=lim

_{x-->a}[tex]\frac{f(x)-f(a)}{x-a}[/tex]

(i) Using Equation 2

m=lim

_{h-->0}[tex]\frac{f(a+h)-f(a)}{h}[/tex]

## Homework Equations

## The Attempt at a Solution

For the first one, I got as far as lim

_{x-->-1}x

^{3}+1/x+1 and was stuck. I thought it was undefined. Then I plugged it into a limit calculator online in desperation, and found that the answer was 3. But for equation 2 I got to the end and go undefined again, plugged it into the limit calculator seeing that it said it was undefined too. I just wanna know how you would go about completing the first one, and I am just a little confused at the point of this exercise. Thanks for any help you guys can give me.
