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

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

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

Prove that sin(2theta)/(1-cos2theta)=cot theta

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

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

Prove the trigonometric identities: (1+cot A+tan A)(sin A-cos A)=(sec A)/(cos ec^(2)A)-(cos ecA)/(sec^(2)A)=sin A tan A-cot A cos A

(sin^(2)A)/(1+cot A)+(cos^(2)A)/(1+tan A)=1-sin A*cos A

Prove that, (1+ cos 2 alpha + sin 2 alpha)/(1-cos 2 alpha +sin 2 alpha)=cot alpha
