math behind the hydrangeas : fractals and geometric sequencesFor the 9-tiled, 6 layer hydrangea: the relationship between the number of bases creased, y, and the grid size, x, can be modeled byy = (1/144)x^2 + (5/9)x + (1/9)Individual hydrangea units are perfect fractals consisting of squares rotated 45° and set inside the previous square. Therefore, the perimeter of each subsequent square is represented byan = (sqrt2/2) to the (n-1)where n is the layer number and an is the perimeter.
