The time it would take to find the determinant of a matrix using the cofactor method can be daunting. A student may not realize this as they may be limited to finding determinants of matrices of order 4×4 or less by hand. In this blog, we derive the formula for a typical amount of computational time it would take to find the determinant of a nxn matrix using the cofactor method.

TANK YOU VERY MUCH I hope you will help me by doing such things from your blogs and websites since I’m an electrical engineering student I want such a simple methods to overcome mathematics and electronics problems and finally what you have done is a great full thing.this is your excellency keep it up!!
