em português, onde posso ser mais claro :)

então, no site eu preciso que pessoas possam fazer certas perguntas (nas áreas de matemática e física, mas ela precisa entrar de maneira simples (e mais visual ou via atalhos) com integrais, derivadas, somatórios e símbolos matemáticos de modo geral.

procurei e não achei nenhuma lib js pra isso, queria saber se alguém conhece alguma coisa pra isso que possa recomendar.

obrigado.
