Understanding Exponential Decay

Exponential decay describes the decrease in quantity over time. It's commonly observed in processes like radioactive decay, drug metabolism, and cooling of objects. The model is represented by the formula:

\( A(t) = A_0 \cdot e^{-\lambda t} \)

\( A(t) \) is the quantity at time \( t \).
\( A_0 \) is the initial quantity when \( t = 0 \) (Initial Value).
\( \lambda \) is the decay constant (Decay Rate), determining how quickly the quantity decreases.
\( e \) is the base of the natural logarithm, approximately 2.718.

This tool estimates \( A_0 \) and \( \lambda \) from your provided data, helping you model and understand exponential decay phenomena. Simply input your time and quantity measurements to get started.
