1. ## differentiation

hi,

I have the function A(t) with its differential equation of dA/dt= -kA

and the solution as a function: A(t)= Ao e^-kt.

I need to find the values of Ao and k in the equation A(t) before i
can continue with the rest of the question.

If anyone can help thank you.

$k$ will be stated somewhere in the question if not leave as a symbolic constant and $A_0$ is the initial condition $A(0)=A_0$ which also should be mentioned in the question if not also leave as a symbolic constant
