WebLearn Chapter 4 Determinants of Class 12 free with solutions of all NCERT Questions for CBSE Maths. Finding Equation of line using Determinants (We use Area of Triangle formula) Suppose equation of matrix is given, like A 2 – 4A + I = O, we need to find A -1 using this equation. (Here we will use property AA -1 = I) Webdeterminants of any order. However, we shall restrict ourselves upto determinants of order 3 only. Property 1 The value of the determinant remains unchanged if its rows and columns are interchanged. Verification Let Δ = 12 3 12 3 12 3 aa a bb b cc c Expanding along first row, we get Δ = 23 1 312 12 3 23 1 312 bb b bbb aa a cc c ccc −+ = a 1 ...

Inverse of a matrix is defined usually for square matrices. For every m × n square matrix, there exists an inverse matrix.If A is the square matrix then A-1 is the inverse of matrix A and satisfies the property:. AA-1 = A-1 A = I, where I is the Identity matrix.. Also, the determinant of the square matrix here should not be equal to zero. grafclean paint
