Type:

Command

 

 

 

 

Description:

Linearizes and simplifies trigonometric expressions. Note that this function does not collect sin

 

and cos terms of the same angle.

 

 

 

 

Access:

PTRIG, Trigonometry, …ÑL

 

 

 

Input:

An expression.

 

 

 

 

Output:

The transformation of the expression.

 

 

 

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:

Linearize and simplify the following:

 

 

 

 

( cos(x))4

 

 

 

 

Command:

TLIN(COS(X)^4)

 

 

 

 

Result:
