gives a primitive:
N o t e
You can also type
which gives the
primitive which is zero for x = 1
Example
Calculate:
Typing:
gives the result:
N O T E :
If the argument to INTVX is the AND of two elements,
INTVX concerns itself only with the second element of the
AND, and adds the result to the first argument.
lim
Calculate limits
LIMIT or lim has two arguments: an expression dependent
on a variable, and an equality (a variable = the value to
which you want to calculate the limit).
You can omit the name of the variable and the sign =,
when this name is in VX).
It is often preferable to use a quoted expression:
