Lesson Objective(s)
  • How can differentiation be used to find the related rates?
Standard(s)
  • APC.5

    • Investigate derivatives presented in graphic, numerical, and analytic contexts and the relationship between continuity and differentiability.

      • The derivative will be defined as the limit of the difference quotient and interpreted as an instantaneous rate of change.

  • APC.6

    • ​The student will investigate the derivative at a point on a curve.

      • Includes:

        • finding the slope of a curve at a point, including points at which the tangent is vertical and points at which there are no tangents

        • using local linear approximation to find the slope of a tangent line to a curve at the point

        • ​defining instantaneous rate of change as the limit of average rate of change

        • approximating rate of change from graphs and tables of values.

  • APC.7

    • Analyze the derivative of a function as a function in itself.

      • Includes:

        • comparing corresponding characteristics of the graphs of f, f', and f''

        • ​defining the relationship between the increasing and decreasing behavior of f and the sign of f'

        • ​translating verbal descriptions into equations involving derivatives and vice versa

  • APC.8

    • Apply the derivative to solve problems.

      • Includes:

        • optimization involving global and local extrema;

        • modeling of rates of change and related rates;

        • use of implicit differentiation to find the derivative of an inverse function;

        • interpretation of the derivative as a rate of change in applied contexts, including velocity, speed, and acceleration; and

  • APC.9

    • Apply formulas to find derivatives.

      • Includes:

        • derivatives of algebraic, trigonometric, exponential, logarithmic, and inverse trigonometric functions

        • derivations of sums, products, quotients, inverses, and composites (chain rule) of elementary functions

        • derivatives of implicitly defined functions

Mathematical Practice(s)
  • #1 - Make sense of problems and persevere in solving them
  • #2 - Reason abstractly and quantitatively
  • #3 - Construct viable arguments and critique the reasoning of others
  • #4 - Model with mathematics
