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

## Statement
Write a `checkLinearIndependence` function that accepts a collection of vectors, $S = \{v_1, v_2, \cdots , v_n\}$, as input and returns either `True` if all vectors are linearly independent or `False` if there are dependent vectors. Assume that the vectors have the same vector space.

## Sample inputs and outputs
The following table provides example inputs (list of vectors or rows of a matrix) and corresponding outputs:
|  Input | Output  |
| :----: | :----: |
| $S:[[5, 3, 2],[6, 7, 8],[5, 3, 2]]$ | `False` |
| $S:[[7, 52, 58],[90, 76, 36],[67, 90, 13]]$ | `True` |
| $S:[[5, 3, 2],[6, 7, 8],[11, 10, 10]]$ | `False` |

## Try it yourself
The signature of the function is given below:
