Show that :
`tan3A - tan2A - tanA = tan3A tan2A tanA`

tan3x-tan2x-tan x=tan3x tan2x tan x

Prove that: tan3A tan2A tan A=tan3A-tan2A-tan Acot A cot2A-cot2A cot3A-cot3A cot A=1

Prove that : (i) "tan"3A-"tan"2A-"tan"A="tan"3A "tan"2A "tan"A (ii) "tan"7A-"tan"5A-"tan"2A="tan"7A "tan"5A "tan"2A (iii) "tan"13 A -"tan" 9A-"tan" 4A ="tan"13 A "tan"9A tan 4A.

Show that tan3x tan2x tan x=tan3x-tan2x-tan x

The value of tan 3A -tan 2A -tan A is equal to (A) tan 3A tan 2A tan A (B)-tan 3A tan 2A tan A (C) tan A tan 2A-tan 2A tan 3A-tan 3A tan A (D) none of these

tan3A-tan2A-tan A= is equal to tan3A-tan2A-tan A tan3.Atan2A tan Atan A tan2A-tan2Atan3A-tan3Atan A None of these

(tan3A+tan A)/(tan3A-tan A)=

Show that tan" "3x" "tan" "2x" "tan" "x" "=" "tan 3x - tan 2x - tan x .
