The index law for multiplying powers is eaeb=e^a e^b=eaeb= [...]\text{[...]}[...].

A
  • PPP: population size
  • dPdt\frac{dP}{dt}dtdP​: individuals added per year
B

The index law for multiplying powers is eaeb=e^a e^b=eaeb= ea+b\boxed{e^{a+b}}ea+b​.

C

For A>0A>0A>0, k>0k>0k>0 gives exponential growth, while k<0k<0k<0 gives exponential decay.

D

If yyy is a function of uuu, and uuu is a function of xxx, then dydx=\frac{dy}{dx}=dxdy​= dydududx\boxed{\frac{dy}{du}\frac{du}{dx}}dudy​dxdu​​.
