Exploring a conformal mapping of the complex plane

This applet illustrates a conformal mapping , . The blue point represents a complex number z. The red point is its image f(z) under the mapping. Drag the point z and see its image change. You can use the checkboxes to explore the effect of the mapping on some regions in the complex plane: 1. a grid of points in a region of the plane 2. a point on a circle centered at 0 3. a point on a ray from 0 Drag the blue point z to see its image f(z) change, shown as the red point.
