Hi
How would you differentiate the following:
2x^2 + 2000/r
I know it would be first 4x + ?UNKNOWN?
Im not sure how to differenctiate 2000/r
Hello,
that depends:
a) If your function reads $\displaystyle f(x) = 2x^2 + \frac{2000}{r}$ then r is considered to be a constant.
b) If your function reads $\displaystyle f(r) = 2x^2 + \frac{2000}{r}$ then x is considered to be a constant.
c) If your function reads $\displaystyle f(t) = 2x^2 + \frac{2000}{r}$ then x and r are considered to be a constant.
According to your rematk it seems to be a)
