Calculus

Focusing on the practical applications of calculus, this book provides a clear overview of its core concepts: differentiation and integration. It demonstrates how calculus can effectively model real-world phenomena through mathematical functions. Notably, it explores its role in statistics, covering topics such as the distinction between mean and median, derivation of least squares formulas for regression coefficients, parameter estimation from theoretical distributions, and calculating statistical p-values using continuous test variables like the t-variable.
