=
(equal)
=
key
Expr1 = Expr2 ⇒ Boolean expression
List1 = List2 ⇒ Boolean list
Matrix1 = Matrix2 ⇒ Boolean matrix
Returns true if Expr1 is determined to be equal to Expr2.
Returns false if Expr1 is determined to not be equal to Expr2.
Anything else returns a simplified form of the equation.
For lists and matrices, returns comparisons element by element.
Note for entering the example: In the Calculator application
on the handheld, you can enter multi-line definitions by pressing @
instead of · at the end of each line. On the computer keyboard,
hold down Alt and press Enter.
Example function that uses math test symbols: =, ƒ, <, {, >, |
Result of graphing g(x)
ƒ (not equal)
/= keys
Expr1 ƒ Expr2 ⇒ Boolean expression
List1 ƒ List2 ⇒ Boolean list
Matrix1 ƒ Matrix2 ⇒ Boolean matrix
Returns true if Expr1 is determined to be not equal to Expr2.
Returns false if Expr1 is determined to be equal to Expr2.
Anything else returns a simplified form of the equation.
For lists and matrices, returns comparisons element by element.
Note: You can insert this operator from the keyboard by typing /=
See “=” (equal) example.
<
(less than)
/= keys
Expr1 < Expr2 ⇒ Boolean expression
List1 < List2 ⇒ Boolean list
Matrix1 < Matrix2 ⇒ Boolean matrix
Returns true if Expr1 is determined to be less than Expr2.
Returns false if Expr1 is determined to be greater than or equal to
Expr2.
Anything else returns a simplified form of the equation.
For lists and matrices, returns comparisons element by element.
