Single variable calculus

At its core, calculus is nothing more than the study of relationships and change. Having a keen grasp of calculus will help you better understand how deep learning algorithms work and how to make them work better for you as a practitioner.

Let's move on to understanding what makes calculus such a powerful tool. We start with single variable calculus, which is about functions that take in a single input and produce a single output.

Derivatives

To start with, let's imagine a straight line with the following equation:

In the equation, the following aspects apply:

• y is a function of x, often written simply as f(x) (which is the notation we will be predominantly using in the remainder of the...
