Homework Statement
Find the slope of the tangent line to the curve y=x3 at point (-1,-1)
(i) Using Definition 1
m=limx-->a[tex]\frac{f(x)-f(a)}{x-a}[/tex]
(i) Using Equation 2
m=limh-->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 limx-->-1x3+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 want to 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.
