Functions that Use Delayed Simplification
Functions that use delayed simplification have a required var argument that performs the
function with respect to a variable. These functions have at least two arguments with the
general form:
function(
expression, var
[, ... ]
)
Note:
Not all functions that use a var argument use delayed simplification.
For a function that uses delayed simplification:
1. The
var
variable is simplified to the lowest level at which it remains a variable (even if
it could be further simplified to a non-variable value).
2. The function is performed using the variable.
3. If
var
can be further simplified, that value is then substituted into the result.
Note:
You may or may not want to define a numeric value for
var
, depending on the
situation.
For example:
solve(x^2
N
x
N
2=0,x)
d
(x^2
N
x
N
2,x)
‰
(x^2
N
x
N
2,x)
limit(x

N
2,x,5)
