Question

Write the value of deteminent lesson 1

Answer 1

Answer:

Let A = [a] be the matrix of order 1, then determinant of A is defined to be equal to a. as: det (A) = |A| = ad – bc. The determinant of a matrix of order three can be determined by expressing it in terms of second order determinants which is known as expansion of a determinant along a row (or a column).
