I will assume u are an indian
then now the only use of those is to get marks and then to show off to your parents that nosy aunties and all that 4 people and all that
keeping funny answers aside it can be used to solve eqn and is used by scientist and mathematicians to solve complex problems

Hey bruh!
matrix is used to represent linear transformations (as is commonly the case in 3D graphics), the determinant effectively represents the degree of unambiguousness inside a matrix.
That is, if determinant is non-zero, the matrix can be inverted because the components don't "cancel out" each other (which would cause zero determinant).
In the same context, transpose of a 3x3 orthogonal rotation matrix is effectively its inverse. This works because the vectors within the 3x3 matrix represent the per-direction scaling factors caused by rotation, and if the vectors represent unique directions with regard to each other......
