How to solve Determinants?

To solve any determinant, we can expand it through any row R or column C. The result of the determinant is independent of it’s expansion through row or column. If any determinant or order n is multiplied by a real number k, the value of determinant become, k^n times the value of determinant.

सारणिकों को हल करना

प्रत्येक सारणिक को हम किसी भी स्तंभ के अनुदिश या फिर किसी भी पंक्ति के अनुदिश प्रसरण करके प्राप्त कर सकते हैं। सरणिक के मान पर किसी पंक्ति या स्तम्भ विशेष का कोई प्रभाव नहीं होता है अर्थात सभी से समान मान प्राप्त होता है। यदि n कोटि वाले किसी सरणिक को किसी संख्या विशेष k से से गुना किया जाए तो उसका मान k^n गुना हो जाता है।

How do we find the determinant of a matrix of order 3 × 3?

Determinant of a matrix of order three can be determined by expressing it in terms of second order determinants. This is known as expansion of a determinant along a row (or a column). There are six ways of expanding a determinant of order 3 corresponding to each of three rows (R1, R2 and R3) and three columns (C1, C2 and C3) giving the same value.

How can we make the determinant expansion easier?

For easier calculations, we shall expand the determinant along that row or column which contains maximum number of zeros.
