Flags: Exact mode must be set (flag –105 clear). Numeric mode must not be set (flag –3 clear). Radians mode must be set (flag –17 set).

Example: Express the result of the following addition in modulo 7. (x2+3x+6)+(9x+3)

Note: Before trying this example, use the CAS modes input form to set the modulo to 7.

Command: ADDTMOD(X^2+3*X+6,9*X+3)

Result: X^2-2*X+2

ADDTOREAL

Type: Command

Description: Adds specified global names to the reserved variable REALASSUME. This is a list of the global variables that will be treated by some CAS operations as real numbers when Complex mode is set. If a variable is already in the REALASSSUME list, this command removes any additional assumptions made on it by ASSUME.

Access:

Catalog, …µ

 

 

Input:

Level 1/Item 1: The name of the global variable to be added to the REALASSUME list, or a list

 

of names.

 

 

Output:

No output in RPN mode, NOVAL in Algebraic mode.

 

Flags:

If the “all variables are real” flag is set (flag –128 set), ADDTOREAL will not add anything to the

 

REALASSUME list, as all variables are assumed real anyway. In this case it will only remove

 

further assumptions made by ASSUME.

Type:

Command

 

 

Description:

Displays a menu or list of CAS algebraic operations.

 

Access:

Catalog, …µ

 

 

Flags:

If the CHOOSE boxes flag is clear (flag –117 clear), displays the operations as a numbered list. If

 

the flag is set, displays the operations as a menu of function keys.

Type:

 

 

Description:

Common Antilogarithm Analytic Function: Returns the common antilogarithm; that is, 10 raised

 

to the given power.

 

 

 

For complex arguments: 10(x,y) = ecx cos cy + i ecx sin cy where c = ln 10.
