    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
