CopyVar
CATALOG
CopyVar
var1
,
var2
Copies the contents of variable var1 to var2. If var2
does not exist,
CopyVar
creates it.
Note:
CopyVar
is similar to the store instruction
( ! ) when you are copying an expression, list,
matrix, or character string except that no
simplification takes place when using
CopyVar
.
You must use
CopyVar
with non-algebraic
variable types such as Pic and GDB variables.

cos(
expression1
)
returns the cosine of the
argument as an expression.
cos(
list1
)
returns a list of the cosines of all
elements in
list1
.
Note: The result is returned as a degree, gradian
or radian angle, according to the current angle
mode setting.
