WebNov 8, 2024 · ln( y y0) = − λt. Using the following property that related the exponential with the natural log: eln ( x) = x, and taking the exponential of each side of the equation and dropping the "prime", we get: y y0 = e − λt. Finally solving to y gives us the expression of how y changes as a function of time: y(t) = y0e − λt.
