When you magnify a 1-dimensional figure by a factor of 2, you get twice as much. If you have Mathematica (or just a CDF player) you should try the accompanying notebook. When you slide **r**, the lengths of the blue arc and gold arc remain equal to...
Your age as a continued fraction is given by the function CFage. It computes the difference between a birth date and the current time. Then this period is measured in years and transformed into a continued fraction. One can also give dates as...
