Exploring areas with hyperbolic and trigonometric functionsThis applet explores a geometric interpretation of the parameter t in the parameterisation of the standard hyperbola using cosh and sinh.
Sequences and seriesThis applet shows the relationship between terms of a sequence and the partial sums of a series. It also allows exploration of some important sequences & series including geometric and harmonic sequences.
Logistic population growthThis applet explores a logistic population growth model with no harvesting. The phase plot is shown alongside the plot of p vs t.
Logistic population growth with harvestingThis applet explores a logistic population growth model with constant harvesting.
Model of a spring with drag and forcingThis applet simulates a spring acting under gravity, subject to drag and an external driving force.
Continuity of a 2-branch piecewise defined functionThis applet investigates the continuity of a 2-branch piecewise-defined function.
Continuity of a piecewise-defined functionThis applet investigates the continuity of a piecewise-defined function.
Exploring an ODEThis applet displays the direction field and solutions for an ordinary differential equation (ODE).
