You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link.

What are the applications of det of a matrix?
it is used to find the inverse of the matrix. inverse(A)= (adj A)/ mod det A
How do you find a variable in a matrix if there is no inverse?
The fact that the matrix does not have an inverse does not necessarily mean that none of the variables can be found.
Prove that a matrix which is both symmetric as well as skew symmetric is a null matrix?
Let A be a matrix which is both symmetric and skew symmetric. so AT=A and AT= -A so A =- A that implies 2A =zero matrix that implies A is a zero matrix

How do you find the inverse of a 10x2 matrix?
A non-square matrix cannot be inverted.
What is the definition of a symmetric matrix?
Symmetric Matrix:Given a square matrix A such that A'=A, where A' is the transpose of A, then A is a symmetric matrix.note: No need to think about diagonal elements, they can be anything.
How do you find original matrix from its inverse matrix?
To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
How do you find inverse of a matrix in Casio fx-991MS scientific calculators?
To find the inverse of a matrix on a Casio fx-991MS scientific calculator, you first need to input the matrix you want to find the inverse of. Then, press the "SHIFT" button followed by the "MODE" button to access the matrix mode. Select the matrix you want to invert by pressing the corresponding number key. Next, press the "SHIFT" button followed by the "MATRIX" button, and then press the "x^-1" button to calculate the inverse of the matrix.
What is the eigen value of a real symmetric matrix?
The eigen values of a real symmetric matrix are all real.
