4434Solving Systems of Equations
http://www.merlot.org/merlot/viewMaterial.htm?id=89895
This applet is used to calculate the solution set to a linear system of equations. Type in the number of equations (this should be thesame as the number of unknowns) and then press "Enter Equations.״A window should pop up with blank text fields where you may enter the coefficients for each variable in the system of equations.The column on the right is for adding the solution values for each of the equations. This table should contain the same values as thecoefficient matrix. After you have filled out each of the text fields, press "done.״Finally, a new window will pop up providing that all of the fields had values entered. This window will contain the values of eachof the unkonwns that the computer solved for.Quick Math - Automatic Math Solutions
http://www.merlot.org/merlot/viewMaterial.htm?id=89913
QuickMath is an automated service for answering common math problems over the internet. Think of it as an online calculator that solves equations and does all sorts of algebra and calculus problems - instantly and automatically! When you submit a question to QuickMath, it is processed by Mathematica, the largest and most powerful computer algebra package available today. The answer is then sent back to you and displayed right there on your browser, usually within a couple of seconds. Best of all, QuickMath is 100% free!EZ Graph
http://www.merlot.org/merlot/viewMaterial.htm?id=91253
Here is Zona Land's graphics calculator, EZ Graph. With it you should be able to graph almost any polynomial, rational, exponential, logarithmic, or trigonometric function. It will allow you to enter variables into your function definition so that you can see the effect of changing coefficients easily.Bisection method
http://www.merlot.org/merlot/viewMaterial.htm?id=75035
This is a Java-enhanced tutorial that allows students to experiment with the bisection method for finding the roots to equations.UML webMathematica
http://www.merlot.org/merlot/viewMaterial.htm?id=79375
A collection of webMathematica scripts on a variety of topics in mathematics including calculus, number theory and abstract algebra. In each script, html form input is processed by a remote version of Mathematica and output is returned. No Mathematica expertise is required other than familiarity with some notation (e. g. Pi for pi ).
