`(1-cos A)/(sin A)=(sin A)/(1+cos A)`

(cos A)/(1+sin A)+(1+sin A)/(cos A)

Prove the following identities: (cos A)/(1-sin A)+(sin A)/(1-cos A)+1=(sin A cos A)/((1-sin A)(1-cos A))((1+cot A+tan A)(sin A-cos A)/(sec^(3)A-cos ec^(3)A)=sin^(2)A cos^(2)A

(cos A)/(1+sin A)+(sin A)/(cos A)=sec A

The minimum value of sin x((1-cos x)/(sin x)+(sin x)/(1-cos x)) is

The value of the expression 1- (sin^(2)y)/(1+ cos y) + (1+ cos y)/(sin y) -(sin y)/(1- cos y) is

(sin A)/(1+cos A)+(sin A)/(1-cos A) is (0^@ (0^@ < A<90^@) की स्थिति में (sin A)/(1+cos A)+(sin A)/(1-cos A) कितना होगा?

(1/(cos A) + (sin A)/(cos A))

(cos A)/(1-sin A)=(1+cos A+sin A)/(1+cos A-sin A)

(cos A)/(1-sin A)=(1+cos A+sin A)/(1+cos A-sin A)

Prove the following identities: (sin+cos A)/(sin A-cos A)+(sin-cos A)/(sin A+cos A)=(2)/(sin^(2)A-cos^(2)A)=(2)/(2sin^(2)A-1)=(2)/(1-2cos^(2)A)
