    vies cognitivo a ideia de intuição... se a memoria, por este modelo, é construída por exaustão de exemplos, a exposição óbvia do algoritmo facilita e acelera o processo de digestão. minha opinião.

    • @julianamaths
      @julianamaths 3 วันที่ผ่านมา

      Se o objetivo fosse "conseguir reproduzir a resolução dos exercícios que foram explicitamente ensinados", provavelmente mandar memorizar essa resolução obteria este efeito mais rapidamente. Eu estou falando de outra situação: quando (1) não se tem pressa, e (2) o objetivo é desenvolver as ferramentas necessárias para conseguir pensar na solução de problemas nesse nível, mas que não foram explicitamente ensinados. Colocar meia dúzia de problemas resolvidos, muito bem memorizados, na cabeça de uma pessoa, é inútil. Era mais fácil escrever uma tabela com as respostas ou pedir para uma máquina fazer. Construir habilidades de pensamento em situações novas, por outro lado, é útil. Mas sim, é mais difícil. Passa por processos que, na opinião de muitos, são mais chatos do que "decore isso". O que eu estou querendo dizer com tudo isso é que eu não necessariamente discordo quando você diz que "facilita e acelera". O que estou dizendo é que facilitar e acelerar não necessariamente são os objetivos. Isso é um problema em toda a matemática, embora estejamos falando de integrais aqui. Você facilita e acelera a soma de frações também quando fala para as crianças memorizarem como faz, e aí 90% da população chega a vida adulta sem saber direito o que é uma fração. Porque na época foi fácil e rápido.

    Determine os coeficientes a, b, c de uma equação quadrática F(x) = ax² + bx + c, em que a ordenada Y (Yv) do vértice é o mesmo valor do coeficiente de termo independente c e F(3) = 2 e F(6) = -4.

    • @julianamaths
      @julianamaths 4 วันที่ผ่านมา

      Se yv=c, então xv=0. Porque c=f(0) e yv=f(xv), mas não tem outro x além do vértice na mesma altura, já que ele é seu próprio reflexo. Daí com xv=0 você já sabe que b=0. Pra pegar a e c faz um sisteminha com esses dois pontos.

      @leosmi1 24 วันที่ผ่านมา

      @@julianamaths minha insistência chata é porque quando aprendemos a famosa y-y_o=m.(x-x_0) a gente usa termos como você mencionou (reta tangente, inclinação da reta, etc). No caso como todos os assuntos da matemática se conversam seria o ideal a comunidade utilizar termos que facilitem ainda mais. Do meu ponto de vista talvez dizer que derivada é uma função de coeficientes de reta seria bacana. Mas daí entra a segunda derivada, que complica um pouco essa visão...

    • @julianamaths
      @julianamaths 23 วันที่ผ่านมา

      Quando você diz "uma função DE", o convencionado é que depois do "de" venha o domínio da função. Como no caso a inclinação da reta tangente é a imagem e não o domínio, o uso de "de" ali seria confuso. Concordo plenamente, o uso de nomenclatura consistente é importante.
