Questions and Answers

What is an ordinary differential equation (ODE)?

  • A differential equation with no unknown function
  • A differential equation with no independent variable
  • A differential equation dependent on multiple independent variables
  • A differential equation dependent on a single independent variable (correct)

What type of differential equation is defined by a linear polynomial in the unknown function and its derivatives?

  • Linear differential equation (correct)
  • Quadratic differential equation
  • Trigonometric differential equation
  • Exponential differential equation

What are the arbitrary differentiable functions in a linear differential equation $a_0(x)y + a_1(x)y' + a_2(x)y'' + ⋯ + a_n(x)y^{(n)} + b(x) = 0$?

  • $b(x)$ only
  • $a_0(x)$ only
  • $a_0(x), a_1(x), ..., a_n(x)$ (correct)
  • $y, y', ..., y^{(n)}$
