Prove that cotA-cosec2A=cot2A

If 2A is not an integral multiple of pi , then show that i) cot A+tan A=2"cosec " 2A ii) cot A-tan A=2 cot2A and deduce the values of tan52 1^(@)/2 and tan37 1^(@)/2

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

The value of (cosec 2A - cot 2A) is-

Given : 4 cot A = 3 , find : "cosec"^2A - cot^2A

Prove that: cotA-cot2A="cosec"2A

Prove that: cotA-cot2A="cosec"2A

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .

simplify (1)/(cosec A-cot A)+(1)/(cosec A+cot A)=?

(1)/(cosec A-cot A)+(1)/(cosec A+cot A)=?
