Blackboard assignments

  1. Trig review: due on September 14, 2017 11:59:00 PM EDT
  2. Parametrization: due on September 17, 2017 11:59:00 PM EDT. Homework cannot be started past this date

Week 1

In the first week, we went over the syllabus and over important rules for the course. By the end of this week, you should have watched all 8 videos below

Furthermore, you should read the following review guide: Trig Review guide. Next, you should complete Set 0   (Set 0 Solutions). Once you your are done reviewing your Trigonometry, you may move on to the following list.

  1. Complete the Trig review and submit your answers on Blackboard. You are allowed 2 attempts. You must submit your solutions by September 14, 2017, 11:59:00 PM EDT.
  2. Read Section 11.1 (parametric curves, see Reading-assignments-sections-11-1-11-3-11-4)
  3. Homework Set 1

Week 2

A plane curve is determined by a pair of parametric equations x=f(t) and y=g(t) where t belongs to some interval I. The pair of relationship x=f(t) and y=g(t) together with the interval I is called a parametrization of the curve.

Examples

  • A line segment starting at (a,b) and ending at (c,d) may be parametrized as follows:  x=a+t(c-a), y=b+t(d-b) and  t\in[0,1].

    line
    Line segment x=1+t, y=1+t, 0≤t≤1
  •  A circle of radius R with center (a,b) has for parametrization  x=a+R \cos(\theta),y=b+R \sin(\theta) for θ∈[0,2π) or θ∈[-π,π)
  • An ellipse with equation \left( x/a\right) ^{2}+\left( y/b\right) ^{2}=1, \text{with} a,b>0 is parametrized as follows x=a \cos(\theta),y=b \sin(\theta) for θ∈[0,2π) or θ∈[-π,π)
  • A cycloid is a curve traced by a point on the circumference of a rolling wheel along a straight line and may be parametrized as x=t-\sin(t),y=1-\cos(t) with t>0.
unitcircle
Parametrizing a unit circle: x=cos(t), y=sin(t)
cycloid
A cycloid: x=1-sin(t) y=1-cos(t)

Just as we use tangent lines to the graph of y=f(x) to determine the rate of change of a function f, we would like to be able to determine how y changes with x when the curve is given by parametric equations. This can be achieved as follows. Let f,g be continuously differentiable functions (their respective first derivatives are continuous). Assume that f′(t)≠0 on some open interval and x=f(t),y=g(t). Then

\dfrac{dy}{dx}=\dfrac{\dfrac{dy}{dt}}{\dfrac{dx}{dt}}

Polar Coordinates

  • Polar to Cartesian: x=r\cos \theta, y=r\sin\theta
  • Cartesian to Polar: r^2=x^2+y^2, \tan \theta =\frac{y}{x}
    • x>0 and \tan\theta=y/x implies that \theta=\arctan(y/x)
    • x=0 and \tan\theta=y/x implies that  \theta=pm \pi/2
    • x<0 and \tan\theta=y/x implies that \theta=\arctan(y/x)+\pi

Area in Polar coordinates

If f is a continuous function, then the area bounded by the polar curve  r=f(\theta)  and the rays \theta=\alpha, \theta=\beta   with  \alpha<\beta   is given by the following formula

 \frac{1}{2}\int_{\alpha}^{\beta}\left( f\left( \theta\right) \right) ^{2}d\theta


Week of  09/25

  • Guidelines for Exam 1 (September 28th) This exam will cover Section 11.1, 11.3 and 11.4.

Spring 2014 Calculus III

Course Description: This class is a standard multivariable calculus which extends the notion of derivative and integral to higher dimensional spaces. It provides ways of understanding motion on planes and 3-dimensional spaces, motion, speed, acceleration, curvature of smooth curves, heat equation, and forces acting on objects… We will also deal with optimization with and without constraints and computations of volume, surface area of solids and computation of arc length. We will also learn how to use different coordinates systems other than the conventional Cartesian coordinates efficiently. Some examples of different coordinate systems will be polar coordinates, cylindrical coordinates, and spherical coordinates system. Ultimately at the end of this course, your thinking skills, problem-solving skills and ability to visualize higher dimensional objects will be greatly enhanced.

Required Text: Calculus: Early Transcendentals by Rogawski, 2nd edition.
