Type:
Command
Description:
Replaces tan(,r) sub-expressions with sin(a:)/(l-cos(2a:)
or (l-cos(2x))/sin(2.x).
Access: Trigonometry, 0011)
Input: An expression
Output:
The transformed expression.
Flags:
Exact mode must be set (flag -105 clear).
Numeric mode must not be set (flag -03 clear).
TAN2SC2
Type:
Corrauand
Description:
Replaces tan(ar) terms in an expression with
sin(2.x)/l+cos(2a;) tenns.
Access: Trigonometry, 0(011)
Input: An expression
Output:
The transformed expression.
Flags: Exact mode must be set (flag -105 clear).
Nmneric mode must not be set (flag -03 clear).
Flag -116 - Prefer sin/cos affects the result:
• If flag -116 is set (Prefer sin()) then Tan(x) tenns are
replaced with:
1 - Cos(2a;)/Sin(2a;)
• If flag -116 is clear (prefer Cos()) then Tan(x) tenns
are replaced witlr:
Sin(2a;)/1 + Cos(20
