1. ### Cylindrical Coordinates Visual (Engineering Maths)

This applet helps visualise the surface generated by cylindrical coordinates using r,θ and z. Click and drag on the sliders on the left to adjust the ranges for r,θ and z. Geogebratube page for this applet
2. ### Spherical Coordinates Visual (Engineering Maths)

This applet visualises surfaces generated by spherical coordinates using r,θ and φ. Click and drag on the sliders on the left to change the values for r,θ and φ. Click and drag on the graph to change/rotate the view. Geogebratube page for this applet
3. ### Solution of the heat equation

This applet shows a solution of the heat equation, a partial differential equation from MAST20029 Engineering Mathematics.
4. ### Sequences and series

This 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.
5. ### Parametric curves

This applet plots and traces a parametric curve, given as a vector function in R2.
6. ### Solution of the wave equation

This applet illustrates a solution of the wave equation, from the MAST20029 Engineering Mathematics lecture notes.
