In this project, you practice loop and defining custom functions. Draw the following shape with a for loop. Define a function draw_circle(x,y,r), which draws a circle centered at (x,y) and
Parametric equations provides a convenient way to draw curves. We will use the following parametric equation in this project. In the equations above, t is the parameter. Let is range
In a previous project, you drew Archimedean Spiral, in which radius increase linearly with the angle. In Fermat’s spiral, radius increases in proportion to the square root of the angle.
