All the functions on this menu are also available on the menu in the Equation Writer. See “DIFF menu” on

page 14-16 for a description of these functions.

Hyperb menu

All the functions on this menu are described in “Hyperbolic trigonometry” on page 13-9.

Integer menu

Note that many integer functions also work with Gaussian integers (a + bi where a and b are integers).
