Invertible matrices
व्युत्क्रमणीय आव्यूह
In Class 12 Mathematics, this topic from the Matrix chapter introduces invertible matrices—square matrices that have a multiplicative inverse. Students learn the condition for invertibility, namely that the determinant is non-zero, and understand how the inverse relates to the identity matrix. They practise finding inverses using the adjoint method and elementary transformations, verify standard properties, and apply matrix inverses to solve systems of linear equations.
