Questions and Answers

What is a partial differential equation (PDE)?

  • An equation containing unknown multi variables with their partial derivatives (correct)
  • An equation containing only one variable and its derivatives
  • An equation containing known variables with their partial derivatives

    • What is the definition of a partial derivative?

  • The derivative of a function of independent variables with respect to one of the variables, without considering the other variables
  • The derivative of a function of dependent variables with respect to one of the variables, assuming the other variables are constant
