you can find the second derivative the same way u found the first, by using the quotient rule where and
hope that helps
Well I tried that, and I got 2x-2 for the second derivative. However, the answer is not that. Where am I going wrong..I used the quotient rule like you said which makes sense.
So, you do it in the same way as the first. Quotient rule, and then you've got a chain rule in the denominator.
alternatively, you can bring the whole bottom up to the top,
-1[(x-1)^-2]
and just do the chain rule, so
-1(-2)[(x-1)^-3] =
2/(x-1)^3
We haven't learned this yet, so I would like to know how to do it without this rule (for ex. using the quotient rule, because I used the q.r. and got the wrong answer)
