Help with both parts please , havent learned if or else statements on mathlab yet so please use basic programmes please .

1. The Spiral of Archimedes (left) may be represented in polar coordinates by the equation r a0. (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, q-1.5, and from-2 to 2t, write some command-line statements to draw the spirals to make the two spirals in the same figure window 2. Use polyfit to find a 4rd degree polynomial to fit the following set of data: Value-4:1:5; Vibration = [-507.6,-261.88,-100.03, -38.08, 6.9, 7.53, 15.6, 51.8, 182, 428.97] Plot the best fitting curve and the data points on the same figure
