Question

What is the derivative of this? I think it involves partial derivatives but I'm not sure? (see image)

Answer 1

Would it be p(q)-C(q) ?

Answer 2

Or would it be 0??? Would you hold p(q) and -C(q) constant and treat them as constants so their deriv. would be 0 cancelling out the derivative of q =1?

Answer 3

I don't think you're taking partial derivatives

Answer 4

you're just deriving with respect to q

so deriving p(q) with respect to q gives you p'(q)

deriving p(q)*q with respect to q gives:

p'(q)*q + p(q)*1 ---> p'(q)*q+p(q)

I'm using the product rule

Answer 5

deriving C(q) with respect to q gives C'(q)

Answer 6

hopefully this is making sense

Answer 7

Great sense of what it means to take the derivative of a function with respect to a variable

Answer 8

Oh! Thank you I understand. I was over thinking this and trying to do something else completely.

Answer 9

you're welcome
