Notes about Using Math Functions with Lists
A list can be used to input several values for certain functions. (Other
chapters and Appendix A state if a list is valid.) The function is evaluated
for each element in the list, and a list is returned.
¦
If a list is used with a function, the function must be valid for every
element in the list, except in graphing. (In graphing, an invalid element
in a list, such as
M
1
in
‡
{1,0,
M
1}
, is simply ignored.)
)
This returns an error.

.
¦
If two lists are used with a two-argument function, the length of the lists
must be the same. The answer is a list in which each element is
calculated by evaluating the function using the corresponding elements
in the lists.

If a list and a value are used with a two-argument function, the value is
used with each element in the list.
