Type: Command
Description: Recalls the nth answer from history (algebraic mode only), where n is an integer. In RPN mode, it
performs the LASTARG command.
Access: !î ( îis the left-shift of the `key).

APPLY
Type: Function
Description: Apply to Arguments Function: Creates an expression from the specified function name and
arguments.
A user-defined function f that checks its arguments for special cases often can
't determine
whether a symbolic argument x represents one of the special cases. The function f can use
APPLY to create a new expression f(x). If the user now evaluates f(x), x is evaluated before f, so
the argument to f will be the result obtained by evaluating x.
When evaluated in an algebraic expression, APPLY evaluates the arguments (to resolve local
names in user-defined functions) before creating the new object.

ARC
Type: Command
Description: Draw Arc Command: Draws an arc in PICT counterclockwise from x
θ
1
to x
θ
2
, with its center at
the coordinate specified in argument 1 or level 4 and its radius specified in argument 2 or level 3.
ARC always draws an arc of constant radius in pixels, even when the radius and center are
specified in user-units, regardless of the relative scales in user-units of the x- and y-axes. With
user-unit arguments, the arc starts at the pixel specified by (x, y) + (a, b), where (a, b) is the
rectangular conversion of the polar coordinate (x
radius
, x
θ
1
). The resultant distance in pixels from
the starting point to the centre pixel is used as the actual radius, r'. The arc stops at the pixel
specified by (r', x
θ
2
).
