  • Calculus Lab 4—Difference Quotients and Derivatives (Edited from U. Of
    Calculus Lab 4—Difference Quotients and Derivatives (edited from U. of Alberta) Objective: To compute difference quotients and derivatives of expressions and functions. Recall Plotting Commands: plot({expr1,expr2},x=a..b); Plots two Maple expressions on one set of axes. plot({f,g},a..b); Plots two Maple functions on one set of axes. plot({f(x),g(x)},x=a..b); This allows us to plot the Maple functions f and g using the form of plot() command appropriate to Maple expressions. If f and g are Maple functions, then f(x) and g(x) are the corresponding Maple expressions. The output of this plot() command is precisely the same as that of the preceding (function version) plot() command. 1. We begin by using Maple to compute difference quotients and, from them, derivatives. Try the following sequence of commands: 1 f:=x->1/(x^2-2*x+2); This defines the function f (x) = . x 2 − 2x + 2 (f(2+h)-f(2))/h; This is the difference quotient of f at the point x = 2. simplify(%); Simplifies the last expression. limit(%,h=0); This gives the derivative of f at the point where x = 2. Exercise 1: Find the difference quotient and derivative of this function at a general point x (hint: make a simple modification of the above steps). This f (x + h) − f (x) means find and f’(x). Record your answers below. h Use this to evaluate the derivative at the points x = -1 and x = 4. (It may help to remember the subs() command here; for example, subs(x=1,e1); means substitute x = 1 into the expression e1).

  • Numerical Differentiation
    Chapter 11 Numerical Differentiation Differentiation is a basic mathematical operation with a wide range of applica- tions in many areas of science. It is therefore important to have good meth- ods to compute and manipulate derivatives. You probably learnt the basic rules of differentiation in school — symbolic methods suitable for pencil-and-paper calculations. Such methods are of limited value on computers since the most common programming environments do not have support for symbolic com- putations. Another complication is the fact that in many practical applications a func- tion is only known at a few isolated points. For example, we may measure the position of a car every minute via a GPS (Global Positioning System) unit, and we want to compute its speed. When the position is known at all times (as a mathematical function), we can find the speed by differentiation. But when the position is only known at isolated times, this is not possible. The solution is to use approximate methods of differentiation. In our con- text, these are going to be numerical methods. We are going to present several such methods, but more importantly, we are going to present a general strategy for deriving numerical differentiation methods. In this way you will not only have a number of methods available to you, but you will also be able to develop new methods, tailored to special situations that you may encounter. The basic strategy for deriving numerical differentiation methods is to evalu- ate a function at a few points, find the polynomial that interpolates the function at these points, and use the derivative of this polynomial as an approximation to the derivative of the function.

  • 2.1 the Derivative and the Tangent Line Problem
    96 Chapter 2 Differentiation 2.1 The Derivative and the Tangent Line Problem Find the slope of the tangent line to a curve at a point. Use the limit definition to find the derivative of a function. Understand the relationship between differentiability and continuity. The Tangent Line Problem Calculus grew out of four major problems that European mathematicians were working on during the seventeenth century. 1. The tangent line problem (Section 1.1 and this section) 2. The velocity and acceleration problem (Sections 2.2 and 2.3) 3. The minimum and maximum problem (Section 3.1) 4. The area problem (Sections 1.1 and 4.2) Each problem involves the notion of a limit, and calculus can be introduced with any of the four problems. A brief introduction to the tangent line problem is given in Section 1.1. Although partial solutions to this problem were given by Pierre de Fermat (1601–1665), René Descartes (1596–1650), Christian Huygens (1629–1695), and Isaac Barrow (1630–1677), credit for the first general solution is usually given to Isaac Newton (1642–1727) and Gottfried Leibniz (1646–1716). Newton’s work on this problem ISAAC NEWTON (1642–1727) stemmed from his interest in optics and light refraction. In addition to his work in calculus, What does it mean to say that a line is Newton made revolutionary y contributions to physics, including tangent to a curve at a point? For a circle, the the Law of Universal Gravitation tangent line at a point P is the line that is and his three laws of motion.
