Linear algebra is a fundamental pillar of data science. In advanced models in data science, like neural networks, the inputs and transformations are based upon vectors, matrices, and tensors which require a reasonable understanding of linear algebra to get the desired results. It is elegant and the most applied mathematics under the umbrella of data science.

This course teaches linear algebra with a focus on data science. This course encompasses several engaging illustrations, including static images and animations. Furthermore, this course presents mathematical modeling through programming in Python. This course contains several executable coding playgrounds on real data sets and a final project with practical applications.

Aside from theoretical implementations, the modern-day world needs its daunting calculations, trajectory mapping, and distance manipulation, all of which linear algebra provides. By the end of this course, you’ll have a working knowledge of all the necessary teachings in linear algebra.

Linear Algebra for Data Science Using Python

## Determinant
The **determinant** of a matrix helps represent a matrix in the form of a number. This number gives a lot of important information about the matrix, including its singularity. Unlike _rank_, which can be calculated for a matrix of any dimension and is always positive, a _determinant can only be calculated_ for square matrices and can have any scalar value. Determinants are written in two different ways:
$$det(A) \qquad or \qquad |A|$$
The Python function to calculate the determinant of a square matrix is available in the `numpy` library.
