  • Unit 3: Derivatives

    In this unit, we start to see calculus become more visible when abstract ideas such as a derivative and a limit appear as parts of slopes, lines, and curves. Then, there are circles, ellipses, and parabolas that are even more geometric, so what was previously an abstract concept can now be something we can see. Nothing makes calculus more tangible than to recognize that the first derivative of an automobile's position is its velocity and the second derivative of that position is its acceleration. We are at the very point that started Isaac Newton on his quest to master this mathematics, what we now call calculus, when he recognized that the second derivative was precisely what he needed to formulate his Second Law of Motion  F = MA , where  F is the force on any object,  M is its mass, and  A is the second derivative of its position. Thus, he could connect all the variables of a moving object mathematically, including its acceleration, velocity, and position, and he could explain what really makes motion happen.

    Completing this unit should take you approximately 42 hours.

    • Upon successful completion of this unit, you will be able to:

      • state the definition of a derivative of a function  f(x) ;
      • recognize and use the common equivalent notations for the derivative;
      • state the graph and rate meanings of a derivative;
      • estimate a tangent line slope and instantaneous rate of change from the graph of a function;
      • write the equation of the line tangent to the graph of a function  f(x) ;
      • calculate the derivatives of the elementary functions;
      • calculate second and higher derivatives and state what they measure;
      • differentiate compositions of functions using the chain rule;
      • calculate the derivatives of functions given as parametric equations and interpret their meanings geometrically and physically;
      • state whether a function, given by a graph or formula, is continuous or differentiable at a point or on an interval;
      • solve related rate problems using derivatives;
      • approximate the solutions of equations by using derivatives and Newton's method;
      • approximate the values of difficult functions by using derivatives;
      • calculate the differential of a function using derivatives and show what the differential represents on a graph; and
      • calculate the derivatives of really difficult functions by using the methods of implicit differentiation and logarithmic differentiation.
