Vector equations of lines in R3
This applet shows a line in R3 and the vector form of its equation.melbapplets.ms.unimelb.edu.au/2023/02/01/vectorequationsoflinesinr3

Visualising row addition on a 3×3 matrix
This applet shows how the determinant is unaffected by the elementary row operation of addition of a scalar multiple of a row to another row.melbapplets.ms.unimelb.edu.au/2023/02/01/visualisingrowadditionona3x3matrix

Visualising row addition on a 2×2 matrix
This applet shows how the determinant is unaffected by the elementary row operation of addition of a scalar multiple of a row to another row.melbapplets.ms.unimelb.edu.au/2023/02/01/visualisingrowadditionona2x2matrix

Visualising row, column and solution spaces
This applet shows the row, column, and solution spaces of a 3x3 matrix M.melbapplets.ms.unimelb.edu.au/2023/02/01/visualisingrowcolumnandsolutionspaces

Columns of a matrix and the ranknullity theorem
This applet shows how the column space, solution space, rank and nullity of a matrix M change as you append additional columns. Initially the matrix M has a single column. You can add extra columns to M by editing the text boxes on the right of the applet, and clicking the ‘Append column’ button.

Exploring areas with hyperbolic and trigonometric functions
This applet explores a geometric interpretation of the parameter t in the parameterisation of the standard hyperbola using cosh and sinh.melbapplets.ms.unimelb.edu.au/2023/02/01/exploringareaswithhyperbolicandtrigonometricfunctions

Tangency: chords, tangents and velocity of a parametric curve
This applet explores the velocity vector of a parametric curve, and its relationship to the chord r(t+h)r(t) and the difference quotient.melbapplets.ms.unimelb.edu.au/2021/08/19/tangencychordstangentsandvelocityofaparametriccurve

Confidence intervals, hypothesis testing and pvalues
This applet illustrates the connection between a confidence interval, a formal hypothesis test, and the pvalue of a hypothesis test.melbapplets.ms.unimelb.edu.au/2021/07/12/confidenceintervalshypothesistestingandpvalues

Power of a hypothesis test
This applet gives a visualisation of the concept of statistical power, and helps illustrate the relationship between power, sample size, standard deviation and difference between the means.melbapplets.ms.unimelb.edu.au/2021/07/12/powerofahypothesistest

Partitioning of variability in regression
This applet illustrates partitioning of variability into explained (fitted) and unexplained (residual) variability.melbapplets.ms.unimelb.edu.au/2021/07/12/partitioningofvariabilityinregression
