Price Elasticity, Partial Derivative

  • #1
Hi all,

I've got a question regarding a price elasticity problem and a partial derivative.
That's what's given for the exercise:

So, first of all we calculate all the demand with the given information. Which is:

And then we come to the actual problem. (4. b) )

How do they get the partial derivative here? I assume that they are using the quotient rule, right? I would be really glad for a step by step explanation.

Thank you so much!

Hello there,

You should write your questions (Using the template btw, which you did not use!) instead of showing us images. This is because PF can't be sure that those images will stay up, and if they don't, then this thread will be of no use.

I believe somewhere in the PF guidelines, you can read what I just said.
