AndPic CATALOG
AndPic picVar[, row, column]
Displays the Graph screen and logically
“ANDS” the picture stored in picVar and the
current graph screen at pixel coordinates
(row, column).
picVar must be a picture type.
Default coordinates are (0,0), which is the
upper left corner of the screen.

angle() MATH/Complex menu
angle(expression1) ⇒ expression
Returns the angle of expression1, interpreting
expression1 as a complex number.
Note: All undefined variables are treated as
real variables.
In Degree angle mode:
angle(0+2i) ¸90
In Radian angle mode:
angle(1+i) ¸p

angle(z) ¸
angle(x+ iy) ¸
angle(list1) ⇒ list
angle(matrix1) ⇒ matrix
Returns a list or matrix of angles of the
elements in list1 or matrix1, interpreting each
element as a complex number that
represents a two-dimensional rectangular
coordinate point.
In Radian angle mode:
angle({1+2i,3+0i,0ì4i}) ¸
