`tan A + cot A = 2 cosec 2A`

Total number of solutions of tan x + cot x=2cosec x in [-2pi,2pi] is equal to

Prove that: "tan"A+cotA=2"cosec" 2A and deduce that "tan" 75^(@)+cot 75^(@)=4 .

(tan A+cot A)=(sec A*csc A)

Find the general solution of cot x + tan x = 2 cosec x

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 ?

If cosec A + sec A = cosec B + sec B then prove that tan A tan B = cot "" (A + B)/(2) .

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec A)

If : cot theta + tan theta = 2 cdot csc theta =

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .
