Embora pare\u00e7a um resumo banal, ele carrega informa\u00e7\u00f5es estruturais profundas: o tra\u00e7o \u00e9 igual \u00e0 soma dos <em>autovalores<\/em> da matriz, contando as multiplicidades. Para uma matriz 2 \u00d7 2 \\(A\\) com autovalores \\(\\lambda_1\\) e \\(\\lambda_2\\), vale sempre \\(\\operatorname{tr}(A) = \\lambda_1 + \\lambda_2\\), enquanto o determinante d\u00e1 \\(\\det(A) = \\lambda_1 \\lambda_2\\). \u00c9 por isso que o tra\u00e7o aparece constantemente no polin\u00f4mio caracter\u00edstico, na an\u00e1lise de estabilidade de sistemas din\u00e2micos e na mec\u00e2nica qu\u00e2ntica, onde o tra\u00e7o de um operador fornece o valor esperado de um observ\u00e1vel.<\/p>\n<p>O tra\u00e7o tamb\u00e9m tem propriedades alg\u00e9bricas convenientes, que o tornam uma ferramenta essencial em demonstra\u00e7\u00f5es e c\u00e1lculos com matrizes:<\/p>\n<ul>\n<li><strong>Linearidade:<\/strong> \\(\\operatorname{tr}(A + B) = \\operatorname{tr}(A) + \\operatorname{tr}(B)\\) e \\(\\operatorname{tr}(cA) = c\\,\\operatorname{tr}(A)\\).<\/li>\n<li><strong>Propriedade c\u00edclica:<\/strong> \\(\\operatorname{tr}(ABC) = \\operatorname{tr}(BCA) = \\operatorname{tr}(CAB)\\), o que implica \\(\\operatorname{tr}(AB) = \\operatorname{tr}(BA)\\) mesmo quando \\(AB \\neq BA\\).<\/li>\n<li><strong>Invari\u00e2ncia por semelhan\u00e7a:<\/strong> se \\(B = P^{-1}AP\\), ent\u00e3o \\(\\operatorname{tr}(B) = \\operatorname{tr}(A)\\).

Em teoria dos grafos, o tra\u00e7o de \\(A^k\\) conta os passeios fechados de comprimento \\(k\\) no grafo descrito por \\(A\\).<\/p>\n<h2>Premissas e dicas pr\u00e1ticas<\/h2>\n<p>Esta calculadora funciona com matrizes 2 \u00d7 2 e 3 \u00d7 3 e aceita qualquer n\u00famero real como elemento, incluindo negativos e decimais.
