`2 tab x+sec x-3 cot x`

(i) 4 cot x - 1/2 cos x + 2/cosx - 3/sin x + ( 6 cot x)/(cosecx) + 9 (ii) -5 tan x + 4 tan x cos x -3 cotx sec x + 2 sec x -13

Prove the following: cot x cot 2x -cot 2x cot 3x -cot 3x cot x = 1

Prove that cot 2x cot x- cot 3x cot 2x - cot 3x cot x=1

Show that cot 2x cot x - cot 3x cot 2x -cot x=1

int (dx)/(tan x+ cot x+ sec x+ cosec x)

( cot x)/( cot x- cot 3x)+ ( tan x)/( tan x- tan 3x)=

The value of sec x+2 cot 2x sin x lines in

int (sec x cosec x)/(2 cot x- sec x cosec x)dx=

cotx cot 2x - cot 2x cot 3x - cot 3x cot x = 1

cot x cot 2x - cot 2x cot 3x - cot 3x cot x=1
