1. (The shells of a class of animals called nummulites grow in this way) The logarithmic spiral (right) describes the shell growth of the periwinkle and the nautilus. Its equation in polar coordinates is r aq. If we can sign a -2,q1.5, and 0 from-2t to 2t, write some command-line statements to dra the spirals to make the two spirals in the same figure window. The Spiral of Archimedes (left) may be represented in polar coordinates by the equation r -a0. 90 30 20 10 90 15 120 60 120 60 10 30 30 150 150 180 0 180 210 330 210 330 240 300 240 300 270 270
