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.
The keys with each associated math function are described
below. Refer to the usage diagram in the Appendix for the
parameters for each sub-menu item.
