#### 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.

## Activity 11.01: Finding the Minimum of a Surface

Solution:

1. We need to import the `random` module to use its `uniform` function, which chooses a random decimal value in a given range:
```import random
from math import sin, cos,sqrt,pi```
2. Create a function that will provide us with partial derivative of `f` with respect to `u` at (`v,w`):
```def partial_d(f,u,v,w,num=10000):
"""returns the partial derivative of f
with respect to u at (v,w)"""
delta_u = 1/num
try:
if u == 'x':
return (f(v+delta_u,w) - f(v,w))/delta_u
else:
return (f(v,w+delta_u) - f(v,w))/delta_u
except...```
