Exponential Decay Test Quiz
Exponential decay is an abstract mathematical phenomenon which explains why some numbers decrease at a rate directly proportional to their present value. This can be expressed using Calculus. It can also be represented symbolically. This phenomenon is widely applied. Especially in natural sciences, the principle of exponential decay is useful. Do you understand it?
