Draw circles, arcs, angles and other regions on Argand diagram.

The TI Nspire CAS proves incredibly useful for visualizing and shading regions within a complex plane. You can utilize it effectively for tasks like plotting single curves, determining region intersections, and identifying points of intersection. Master the techniques for sketching circles, arcs, lines, perpendicular bisectors, rays, half-planes, and other geometric elements. These skills will significantly enhance your ability to tackle both multiple-choice and extended response questions on your final examination, particularly for Units 1-4.
