Exploring Exponential Growth and Decay

The video tutorial covers exponential growth and decay, starting with a calculus-based derivation of the formula. It explains the process of solving differential equations to model exponential growth or decay. The tutorial includes examples, such as population growth and weight increase, to demonstrate the application of the formula in real-world scenarios.
