-1-1Introduction to Calculus Applets
https://www.merlot.org/merlot/viewMaterial.htm?id=343859
<p>This site consists of several dozen applets, each pertaining to a different aspect of single variable Calculus. Topics covered range from continuity and limits to differential equations and infinite series. Each applet is on a separate page that also includes detailed explanations of the concept under review along with suggestions for student experimentation with the applet. Each applet can be opened in a resizable window for better viewing as a classroom demonstration.</p>Sun, 12 Oct 2008 00:09:46 GMTThomas DowneyPopulation Modeling Applet
https://www.merlot.org/merlot/viewMaterial.htm?id=314085
<p>In this applet, the user applies Euler's Method to modeling population growth using the Malthus exponential model and the Verhulst constrained growth model. After finding the Euler solution, the user can check the solution with the Adaptive Euler Approximation or with a slope field. Also, the user can enter an exact solution obtained from separating variables (or whatever) and again check the Euler solution graphically.</p>Tue, 03 Jun 2008 14:04:20 GMTDon Kreider; Dwight Lahr Department of Mathematics, Dartmouth College; Department of Mathematics, Dartmouth CollegeFunctions Defined by Series

https://www.merlot.org/merlot/viewMaterial.htm?id=83200
<p>The goal of this site is to visualize the mathematical structure behind M.C. Escher's picture called "Print Gallery" (1956). The visualization itself is largely non-mathematical and is accomplished through many still images and animations. The actual mathematics, involving conformal mappings of the complex plane, is contained in a pdf copy of the original AMS publication. The Droste Effect refers to any image that contains itself on a smaller scale.</p>Mon, 28 Feb 2005 08:00:00 GMTBart De Smit; Hendrik W.

https://www.merlot.org/merlot/viewMaterial.htm?id=314427
<p>Quoted from the site: This applet explores fitting a polynomial p(x) of degree n to a given set of data points. It computes the best least squares approximation to the data, "best" in the sense that SUM (p(xi) - yi)^2 is minimized. The applet provides controls for choosing the degree n, setting the precision of all displayed numbers, selecting and deselecting data points, and editing the data list. It also allows for entry of your own custom polynomial and computing its least squares error.</p>Wed, 04 Jun 2008 20:06:21 GMTDon Kreider; Dwight Lahr Department of Mathematics, Dartmouth College; Department of Mathematics, Dartmouth CollegeMath Applets at SLU - Below Calculus

<p>In this applet, the user selects or inputs a function and chooses a point x = a at which to check continuity. The applet will calculate several dozen values of f(x) near x = a. From this data, which is presented both in a table and in a graph, the user can make a conjecture regarding continuity at x = a. Limits at infinity are also considered.</p>Tue, 03 Jun 2008 12:51:40 GMTDwight Lahr; Don Kreider Department of Mathematics, Dartmouth College; Department of Mathematics, Dartmouth CollegeTaylor Polynomial Approximation Applet
