augment() MATH/Matrix menu
augment( list1, list2 ) ⇒ list
Returns a new list that is list2 appended to
the end of list1 .
augment({1,л3,2},{5,4}) ¸
{1 л3 2 5 4}
augment( matrix1 , matrix2 ) ⇒ matrix
augment( matrix1 ; matrix2 ) ⇒ matrix
Returns a new matrix that is matrix2
appended to matrix1 . When the “,” character
is used, the matrices must have equal row
dimensions, and
matrix2 is appended to
matrix1 as new columns. When the “;”
character is used, the matrices must have
equal column dimensions, and
matrix2 is
appended to matrix1 as new rows. Does not
alter matrix1 or matrix2 .

avgRC() CATALOG
avgRC( expression1 , var [ , h ] ) ⇒ expression
Returns the forward-difference quotient
(average rate of change).
expression1 can be a user-defined function
name (see Func ).
h is the step value. If h is omitted, it defaults
to 0.001.
Note that the similar function nDeriv() uses
the central-difference quotient.
avgRC(f(x),x,h) ¸
f(x+h) - f(x)

avgRC(x^2ìx+2,x,3) ¸ 2ø(x+1)
4 Bin MATH/Base menu
integer1 4 Bin ⇒ integer
Converts integer1 to a binary number. Binary
or hexadecimal numbers always have a 0b or
0h prefix, respectively.
256 4Bin ¸ 0b100000000
0h1F 4Bin ¸ 0b11111
0b binaryNumber
0h hexadecimalNumber
Without a prefix, integer1 is treated as
decimal (base 10). The result is displayed in
binary, regardless of the
Base mode.
If you enter a decimal integer that is too large
for a signed, 32-bit binary form, a symmetric
modulo operation is used to bring the value
into the appropriate range.
A binary number can have up to
32 digits. A hexadecimal number
can have up to 8.
Zero, not the letter O, followed by b or h.
