Hello Readers,
Welcome to Week 3 of our Linear Algebra refresh series. This week, we're delving into the world of determinants.
Determinants are a special numerical value calculated from a square matrix. They are like the 'DNA' of the matrix, containing a lot of information about it. Determinants have several applications, including solving systems of equations, finding the inverse of a matrix, and determining whether a matrix is singular or nonsingular.
The determinant of a 2x2 matrix is straightforward to calculate. For a matrix [a b; c d], the determinant is (ad - bc).
For larger square matrices, the calculation involves breaking the matrix down into smaller matrices and using recursion. This process is known as expansion by minors or cofactor expansion.

// Your implementation here
}
Remember, understanding determinants is a key part of mastering linear algebra. It might seem complex at first, but with consistent practice, it will become second nature.
Keep practicing, and see you next week for more Linear Algebra refresh!
I hope this blog post helps you in understanding and calculating determinants. Remember, practice is key when it comes to mastering these concepts. Good luck!
