'A=2*X'

 

 

Example 1:

DEFINE stores '2*X' in variable A.

 

Example 2:

'A(X,Y)=2*X+3/Y' DEFINE creates a user-defined function A. The contents of A is

 

the program « → X Y '2*X+3/Y' »

DEG

Command

 

 

 

 

 

 

Type:

 

 

 

 

 

 

Description:

Degrees Command: Sets Degrees angle mode.

 

 

 

DEG clears flags –17 and –18, and displays the DEG annunciator.

 

In Degrees angle mode, real-number arguments that represent angles are interpreted as degrees,

 

and real-number results that represent angles are expressed in degrees.

Access:

!&HANGLE DEG

 

 

 

 

 

 

 

!°LMODES ANGLE DEG ( °is the left-shift of the Nkey).

DEGREE

 

 

 

 

 

 

 

 

Type:

Function

 

 

 

 

 

 

Description:

Returns the degree of a polynomial expression. Returns 0 for a constant expression, but –1 if the

 

expression is zero.

 

 

 

 

 

 

Access:

Catalog, …µ

 

 

 

 

 

 

Input:

Level 1/Argument 1: A polynomial expression or equation; all powers must be integers or real

 

numbers with no fractional part.

 

 

 

 

Output:

Level 1/Item 1: An integer representing the highest power in the polynomial. If the input

 

contains powers of more than one variable, including the current variable, returns the highest

 

power of the current variable. If the input contains powers of more than one variable, not

 

including the current variable, returns the highest power of the first symbolic variable (one that is

 

not stored in the current directory path). If the input contains powers of more than one variable,

 

and all the variables are stored in the current directory path, returns the highest power of any of

 

the variables.

 

 

 

 

 

 

Flags:

If exact mode is set (flag –105 clear), the result is returned as an integer, otherwise it is returned as

 

a real number.

 

 

 

 

 

 

Example 1:

Find the degree of the polynomial represented by:

 

 

x2-17=x3+2x

 

 

 

 

 

 

Command:

DEGREE(x^2-17=x^3+2*X)

 

 

 

 

Result:
