` (sin 2A )/(1-cos 2A) = cot A.`

Prove that ( sin 2 A )/( 1 - cos 2 A) = cot A

(sin 2x)/(1- cos 2x ) = cot x

prove that (sin2A)/(1-cos2A)=cot A

Prove that (i).(sin 2x)/(1-cos 2x) = cot x" " (ii) .(1- cos 2x)/(1+ cos 2x) = tan^(2) x

(sin 2A)/( 1+ cos 2A) . (cos A)/( 1+ cos A)= ............... A) tan""A/2 B) cot ""A/2 C) sec ""A/2 D) cosec ""A/2

(sin 2 theta)/(1-cos 2 theta)=cot theta

(1-sin A) / (1-sec A) - (1 + sin A) / (1 + sec A) = 2cot A (cos A-cos ecA)

Prove that: (sin2 theta)/(1-cos2 theta)=cot theta

(sin A+sin2A)/(cos A-cos2A)=cot((A)/(2))

Prove that :(1+cot A+tan A)(sin A cos A)=sin A tan A cot A cos A
