Gradient Calculation (Shockwave)
Determine the gradient from two points.
The Straight Line (Java Applet)
Graphs a line using either slope and y-intercept, point and slope or two points.
Parabolas (Java Applet)
Graphs a parabola from coefficients for the equation in both general form, y=ax˛+bx+c, and completed square form, y=a(x-h)˛+k.
Zap It! Game (Shockwave)
Try to adjust the quadratic function, y=ax˛+bx+c, to 'Zap' as many data points as possible.
Unit Circle (Shockwave)
Explore the relationship between the unit circle and the graphs of the sine, cosine, and tangent functions.
Shifting and Scaling Sine and Cosine Curves (Shockwave)
Experiment with the graphs of trigonometric functions of the form y = a sin[b (x - c)] + d.
Relate the equation and graph to amplitude, period, and frequency.
Experiment with logarithms by changing the base.
View the corresponding exponential function as a reflection across the line y = x.
