#### Overview of this book

Are you looking to start developing artificial intelligence applications? Do you need a refresher on key mathematical concepts? Full of engaging practical exercises, The Statistics and Calculus with Python Workshop will show you how to apply your understanding of advanced mathematics in the context of Python. The book begins by giving you a high-level overview of the libraries you'll use while performing statistics with Python. As you progress, you'll perform various mathematical tasks using the Python programming language, such as solving algebraic functions with Python starting with basic functions, and then working through transformations and solving equations. Later chapters in the book will cover statistics and calculus concepts and how to use them to solve problems and gain useful insights. Finally, you'll study differential equations with an emphasis on numerical methods and learn about algorithms that directly calculate values of functions. By the end of this book, you’ll have learned how to apply essential statistics and calculus concepts to develop robust Python applications that solve business challenges.

# Population Growth

Differential equations are useful for finding a formula for the population of people, animals, and bacteria at a certain time; for example:

Figure 12.7: Differential equation to calculate population at time t

This differential equation means the rate of change of y is proportional to y, or the population grows proportional to its amount. This is the definition of population growth rate: a fraction or percentage of the population. The solution is similar to our interest problems involving continuous compounding:

## Exercise 12.06: Calculating the Population Growth Rate – Part 1

In the 1980s, the annual population growth rate in Kenya was 4%. At that rate, how long would it take for the population to double? Follow these steps to complete this exercise:

1. No matter what the starting population, we're looking for t, which makes the factor...
