`cosecA - 2cot2AcosA = 2sinA`

Prove that cosecA-2cot2AcosA=sinA

Prove the following: cosecA-2cot2A.cosA=2sinA

Prove that cosecA-2 cot 2A cos A=2sinA.

Prove that cosecA-2 cot 2A cos A=2sinA.

The value of (cosecA + cotA +1)(cosecA - cotA + 1) - 2cosecA is: (cosecA + cotA +1)(cosecA - cotA + 1) - 2cosecA का मान है :

cosecA=1/sinA and cotA=cosA/sinA prove cosecA-cotA=tan(A/2)

Prove: (cosAcosecA-sinAsecA)/(cosA+sinA)=cosecA-secA

If x = cosecA + cosA and y = cosecA - cosA, then find the value of (2/(x+y))^2 +((x-y)/2)^2 -1 . यदि x = cosecA + cosA और y =cosecA - cosA, तो (2/(x+y))^2 +((x-y)/2)^2 -1 का मान ज्ञात करें:
