` cot 2A + tan A = cot A - cot 2A`

tan A + cot 2A=

tan A-cot A=-2cot2A

tan A + cot A = 2 cosec 2A

Prove that tan A - cot A =-2 cot2A

cot^(2)A-tan^(2)A=4cot2A cos ec2A

Find A , if tan 2A = cot (A-24^@)

cot x-2 cot 2x = tan x

Prove that : (cot A + tan B)/ (cot B + tan A) = cot A tan B

If A is not an integral multiple of (pi)/(2) , prove that (i) tan A + cot A= 2 cosec 2 A (ii) cot A - tan A = 2cot 2A

cot x-2cot2x=tan x
