• 02:33, 26 January 2024 Wikiadmin talk contribs created page Propriedades algébricas dos vetores (Created page with " Os oito axiomas aqui demonstrados permitem validar as operações algébricas com vetores. Cada um esta demonstrado com números reais, uma vez que os vetores estudados em geometria analítica e álgebra linear introdutória estão definidos para coordenadas reais. A validade de todas mostra que os vetores estudados em geometria analítica fazem parte de um espaço vetorial, embora a definição de um espaço vetorial seja normalmente postergada para o curso de álgebra...")
