Assorted Applets

The Web page contains a plethora of interesting resources to help you visualize important mathematical concepts. Most of these are Java applets, which run interactively as plug-ins in your web browser. To use them you must have Java enabled in your browser preferences - by default, it probably is already.

• Some Java applets from MIT’s OpenCourseWare page for 18.013A:
  • Operations on functions
  • Trigonometric functions
  • Slope of a line
  • Derivative and tangent line
  • Constant, linear, quadratic and cubic approximations
  • Numerical integration
  • Polar plotter
  • Curves in two dimensions
• Function and Derivative Animations, by Przemyslaw Bogacki and Gordon Melrose (.avi files, can play e.g. with Windows Media® Player)
• Java applets of secant lines and tangent lines:
  • A smooth function
• Animations of secant lines approaching (or not approaching) tangent lines (by Douglas N. Arnold):
  • At a point of differentiability
  • At a point of non-differentiability (the one-sided derivatives don’t match)
  • At another point of non-differentiability (vertical tangent; the derivative is infinite)
• Constructing functions that are continuous but nowhere differentiable (!), applet from Maths Online
• Chain rule applet
• First and second derivatives applet (by Scott Sarra)
• More first and second derivatives, with parameters you can tweak (applet from Maths Online)
• Zooming in on a tangent line (animation by Douglas N. Arnold)
• Linear approximation of sin x at 0 (applet from UBC Calculus Online)
• Finding a function’s extremum, applet from Maths Online
• Rolle’s theorem and the mean value theorem (applet from IES, Manipula Math)
• Numerical Integration Simulation (by Joseph L. Zachary)
• Direction field applet (by Scott Sarra)
• More direction field applets (from UBC Calculus Online)
• Parametric equation applet (by Scott Sarra)
• Cycloid animation (AVI) (by Przemyslaw Bogacki and Gordon Melrose)
• Cycloid applet (from Maths Online)
• Computing arc length (AVI) (animation by Przemyslaw Bogacki and Gordon Melrose)
• Approximating arc length (applet by Daniel J. Heath)
• Polar curve applet (from IES, Manipula Math)
• Several polar curve animations (by Przemyslaw Bogacki and Gordon Melrose):
  • limacons:
    • r = 1 + sin t (AVI)
    • r = 3 - 2 cos t (AVI)
    • r = 1 + 2 cos t (AVI)
    • r = 3 - sin t (AVI)
  • rose curves:
    • r = 3 cos_(3t)_ (AVI)
    • r = 5 sin_(2t)_ (AVI)
  • spiral: r = t (AVI)
  • circle: r = cos t (AVI)
• Converging and diverging series animations (by Przemyslaw Bogacki and Gordon Melrose):
  • 1 / N^(1/2) (AVI)
  • 1 / N (AVI)
  • 1 / N² (AVI)
  • 1 / N¹⁵ (AVI)
• Numerical tools for computing sequences / series (from Maths Online)
• Power series grapher
