QUOTE

Encloses an expression that should not be evaluated

 

numerically.

 

 

QUOTE(expression)

 

 

Examples

 

 

QUOTE(SIN(45))

F1(X) stores the

 

expression SIN(45) rather than the value of SIN(45).

 

Another method is to enclose the expression in single

 

quotes.

 

 

For example, X^3+2*X

F1(X) puts the

 

expression X^3+2*X into F1(X) in the Function

 

aplet.

 

(where)

Evaluates expression where each given variable is set to

 

the given value. Defines numeric evaluation of a symbolic

 

expression.

 

 

expression(variable1=value1, variable2=value2,...)

 

Example

 

 

3*(X+1)(X=3) returns

12.

Test functions

 

The test functions are logical operators that always return

 

either a 1 (true) or a 0 (false).

<

Less than. Returns 1 if true, 0 if false.

 

value1<value2

≤

Less than or equal to. Returns 1 if true, 0 if false.

 

value1≤value2

= =

Equals (logical test). Returns 1 if true, 0 if false.

 

value1==value2

≠

Not equal to. Returns 1 if true, 0 if false.

 

value1≠value2

>

Greater than. Returns 1 if true, 0 if false.

 

value1>value2
