A common mistake is assuming that if a matrix satisfies its own characteristic equation, then it must be a diagonal matrix or have some other special form.<\/p>\n<p>This understanding is incorrect because the Cayley-Hamilton theorem states that every square matrix satisfies its own characteristic equation. This means that if the characteristic polynomial of a matrix <code>A<\/code> is <code>p(\u03bb) = det(\u03bbI - A)<\/code>, then <code>p(A) = 0<\/code>. This property holds for all square matrices, regardless of their form or diagonalizability.<\/p>\n<p>The accurate explanation is that the Cayley-Hamilton theorem is a fundamental property of matrices that allows expressing higher powers of a matrix in terms of lower powers and the identity matrix. For instance, if <code>A<\/code> is a 3&#215;3 matrix with characteristic polynomial <code>p(\u03bb) = \u03bb^3 + a\u03bb^2 + b\u03bb + c<\/code>, then <code>A^3 = -aA^2 - bA - cI<\/code>. This relationship is useful in simplifying matrix calculations and is a direct consequence of the Cayley-Hamilton theorem.<\/p>\n<h2>Advanced Topics in Cayley-Hamilton Theorem For GATE<\/h2>\n<p>The <strong>Cayley-Hamilton theorem For GATE <\/strong>states that every square matrix satisfies its own characteristic equation.
