Algorithm for pressing keys;
[SHIFT] [FUNCTION NAME] [Value] [=].

Algorithm for pressing keys, in degree mode;

[SHIFT] [FUNCTION NAME] [value] [=].

The value is an arithmetical expression and has to be entered in

nested parantheses, if necessary.

Foe arc sin (-1/2), the sequential order for pressing keys is

[SHIFT] [SIN] [ ( ] [#-#] [ 1 ] [#-:#] [ 2 ] [ ) ] [ = ]

and the display would be

-30..

For arc tan 1, it is

[SHIFT] [TAN] [ 1 ] [=]

and the display would be

45.
