Sin tan cos scientific calculator.So, what is a determinant? It's a number, and we've learned a lot. But why is it useful? Where does it appear? Matrix determinants are very useful and frequently used tools in linear algebra. Whenever we have a matrix and want to understand it, the determinant is one of the first problems we have to solve. For example, every system of linear equations can be Described in terms of matrices, its determinant helps us find solutions, for example, by using Kramer's rule. Also, when we use matrices to describe linear transformations, it is often best to diagonalize them. How do we do this A little? The deciding factor, of course. The determinant of a matrix also tells us whether the matrix has an inverse, and whether the inverse must be approximated by a Moore-Penrose pseudo-inverse. Finally, we usually need the eigenvalues ​​of this transformation. Yes, you guessed it - for that, we also use the determinant. Hopefully, we've managed to convince you that learning the determinant definition is worthwhile. But how do we calculate it? Are there some short, concise determinant formulas for everyday use?
