  2. 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.

  3. 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.

  4. Visualising row, column and solution spaces

    This applet shows the row, column, and solution spaces of a 3x3 matrix M.

  5. Columns of a matrix and the rank-nullity 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. The […]

  6. 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.

  7. 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.

  8. Confidence intervals, hypothesis testing and p-values

    This applet illustrates the connection between a confidence interval, a formal hypothesis test, and the p-value of a hypothesis test.

  9. 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.

  10. Partitioning of variability in regression

    This applet illustrates partitioning of variability into explained (fitted) and unexplained (residual) variability.
