Introduction to differential equations

Learning objectives

  • Distinguish between differential equations and algebraic equations
  • Explain the meaning of each term of a modeling differential equation (DEs tell a story)
  • Recognize and solve  “The Most Important Differential Equation in the World”, the exponential equation \frac{dy}{dt} = k y
  • Approximate the solution of a differential equation using local linear approximations
