`cot^2A-tan^2A=4cot2A cosec2A`

tan A + cot A = 2 cosec 2A

The value of (tan^2 A+cot^2 A-2)- sec^2 A cosec^2 A is: (tan^2 A+cot^2 A-2)- sec^2 A cosec^2 A का मान क्या होगा ?

The expression cosec^(2)A cot^(2)A-sec^(2)A tan^(2)A-(cot^(2)A-tan^(2)A)(sec^(2)A cosec^(2)A-1) is equal to

The expression cosec^(2)A cot^(2)A-sec^(2)A tan^(2)A-(cot^(2)A-tan^(2)A)(sec^(2)A cosec^(2)A-1) is equal to

Show that tan A+cot A=2 cosec 2A

What is the simplified value of ("cosec"^4 A - cot^2 A )-(cot^4 A+ "cosec"^2A) ?

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

prove that tan A+cot A=2 cosec 2A

cosec A -2 cot 2A cos A=

Prove that tan A + cot A = 2 "cosec 2A" .
