The Hidden Function model evaluates a function f(x) with parameters. It is designed to teach function concepts by allowing a teacher to define a function, hide that function in a repackaged jar file, and asking students to find the hidden function. Students vary the independent variable and observe the resulting function value. If the unknown function includes arbitrary parameters (e.g., f(x)=a*x-3) the parameters appear as additional input fields.
The Hidden Function model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run Java archive. Double clicking the ejs_math_HiddenFunction.jar file will run the program if Java is installed. EJS is a part of the Open Source Physics Project and is available in the OSP Collection.
