EquationMatcher provides to the student an opportunity to visually solve various equation types. Among those provided here are linear, parabolic, and trigonometric functions of x . This Applet driver tests the student to solve the roots of a randomly generated quadratic equation. Feedback and examples are provided upon student request. The Applet also discusses the addition and subtraction of angles.
Information regarding the ellipse is displayed via techexplorer.
Sliders let you modify four different variables associated with the sine wave. This Applet accepts functions of theta and plots the curve into a polar coordinate grid. Calculus Area under a Curve , also available in Java only This Applet plots several predefined functions. You can choose whether to use rectangles or trapezoids to approximate the area under the curve, as well as the number of intervals used for the approximation. TangentFinder TM , also available in Java only TangentFinder plots a predefined function.
