Hello,
for continuous compouding (in the exponential growth and decay) the function for interest after t years is:
A(t) = A0*e^rt
A0 should be read A at time 0
in the book, they say when you differentiate this function this is what you get
dA/dt = r*A0*e^rt = rA(t)
I don't see how to do this differentiation to finally come up with rA(t). I am getting something else using implicit differentiation.
Thanks,
Ivan
