The calculator’s Advanced Keyboard is designed so that various advanced-level

expressions can be written quickly with few strokes of the keys.

Note:

The default angle unit for the Advanced mode is radians. The

examples hereafter will therefore feature the radian angle system,

unless otherwise specified.
