Question

Calculate the second and third derivatives of y = z − 4/z

Answer 1

Again, this is just the power rule. Start by rewriting it like this:\[y = z^{1}-4z^{-1}\] and use the power rule

Answer 2

alright, - exponents and sqrts of derivatives scare me

Answer 3

It can seem intimidating, but with practice you'll find that it's very straightforward.

Answer 4

are they both 0?

Answer 5

wait -8z^-3 and 24z^-4

Answer 6

Yes, that's it
