    Pi day activities

    I've just posted two sketches for pi day: (1) a sketch with two animated circle dissections, leading to two different ways to calculate the area of a circle from its radius and circumference, and (2) a how-to sketch that uses piece-wise functions to create an outline of the letter pi, with detailed directions on how to use the enclosed custom tools to create this construction, or to create a piecewise function of your own choice.

    Hi Scott

    Some really cool dissection animations you have there! Am puzzled though why you call the rope dissection the Archimedes Circle Dissection since as far as I can recall, historically this method for deriving the formula for the area of a circle was first used by Hindu mathematicians some time approx. 1000 AD, but I could be wrong.

    Regards

    I've also just added a sketch at http://sketchexchange.keypress.com/s...formula-for-pi on the Madhava-Gregory-Leibniz formula for pi that could be useful for a pi day presentation or activity.

    Thanks, Michael! This would be a neat presentation for students in higher level math classes. I've featured it and other sketches related to pi and circles in honor of pi day on Monday.
