I. NUMBER AND TITLE OF COURSE
Mathematics 264 - Using Technology to Explore Calculus IIIII. REASONS FOR ADDITION TO PRESENT CURRICULA
A. There is a need for students to explore and model mathematics using currently available technology such as programmable graphing calculators and computer algebra systems. Research shows that this is best done with hands-on activities and projects.III. MAJOR OBJECTIVES OF THE COURSEB . When we reviewed our mathematics program in 1993, our outside evaluators strongly encouraged us to incorporate more technology into our calculus sequence as is the norm in many current calculus programs.
A. The students will use a Computer Algebra System to explore and model concepts which are covered in Calculus III. Their understanding of fundamental notions of calculus will be enhanced by their being able to better visualize them.IV. TOPICAL OUTLINEB . The students will write programs to perform mathematical algorithms and to illustrate and apply calculus concepts. This will prepare them for more advanced programming tasks in subsequent courses.
C. The students will use a programmable graphing utility and Computer Algebra Systems to explore and model challenging and thought-provoking mathematical problems.
Notes: Each numbered item typed in boldface below will be the focus of one class session. The sessions are keyed in to the MAT 263 outline.V. BIBLIOGRAPHYA. Sequences/Series
1. Numerical and graphical representations of sequencesB . Other graphing forms and techniquesa. Explore convergence by plotting the pairs (n, an).2. Convergence of infinite sumsb. For y = f(x) where f(n) = an, apply l'Hopital's rule and the first derivative test (for the Monotone Convergence Theorem) to investigate convergence as in MAT 163 and MAT 164.
c. Program recursive sequences such as the Fibonacci sequence, and determine limits and closed forms.
a. Depict infinite series graphically (e.g., geometric diagrams and harmonic dominos).3. Numerical and graphical depictions of power seriesb. Estimate the sum of a convergent series by programming error estimates for special types of series. As a consequence, approximate well-known irrational numbers to any degree of accuracy.
c. Use numerical integration techniques from MAT 164 to check convergence by the integral test.
a. Confirm accuracy of Maclaurin series representations by animating plots of successive partial sums against the plot of the given function.b. By varying the center x=a, determine graphically the best Taylor series for a given function over a finite interval.
c. Program remainder estimates to investigate polynomial approximations of a given function numerically.
4. Polar coordinates and parametric equationsC. Vectors in the plane and in spacea. Graph parametric representations of curves.5. Conic sections and quadric surfacesb. Explore CAS options for customizing graphs.
c. Visualize and determine the area between polar curves.
a. Write programs to express conic sections and quadric surfaces in standard form.b. Graph conic sections and quadric surfaces. Investigate quadric surfaces further by rotating their graphs and by plotting their level curves.
6. Vector operationsD. Partial differentiationa. Verify the laws of dot and cross product symbolically.7. Lines and planesb. Visualize and compute the area of a triangle and the volume of a parallelepiped.
c. Animate the parametric plot of a line in vector form (as x(t) moves along the line).
a. Graph lines and planes, and determine the angles between them.8. Vector calculusb. Program the vector methods for measuring distance from a point to a line, and from a point to a plane.
a. Investigate limits, derivatives and integrals of vector-valued functions symbolically.b. Analyze the motion of a particle along a curve (i.e., graph, and calculate velocity, acceleration, curvature, as well as unit tangent and unit normal vectors).
9. Visual and numerical representations of higher dimensional functionsE. Multiple integrationa. Graph z = f(x, y) with various plotting options. Compare with several level curves.10. Differentiation in higher dimensionsb. Investigate limits and continuity of functions of several variables.
a. Estimate partial derivatives graphically, and compute Hem symbolically.11. Optimizationb. Verify the chain rules symbolically.
c. Plot a function along with its tangent plane and normal line at a given point.
a. Determine and classify the critical points of a given function by the second derivative test as well as by graphical inspection.b. Solve constrained optimization problems with Lagrange multipliers.
12. Volumes and surface areasa. Compute multiple integrals numerically as well as symbolically.13. Integrals over curves and surfacesb. Visualize and estimate volumes and surface areas of solids determined by functions over rectangular and nonrectangular regions.
c. Convert multiple integrals to polar, cylindrical, or spherical coordinates in order to achieve 12(a) and 12(b) above.
a. Symbolically integrate scalar functions over curves and the tangential and normal components of a vector field along a curve.b. Integrate scalar functions over surfaces and vector fields over oriented surfaces.
c. Program computing the area of any polygon using Green's theorem.
