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

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

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

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

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

Prove that the identities,sin^(-1)cos(sin^(-1)x)+cos^(-1)sin(cos^(-1)x)=(pi)/(2)|x|<=1

Prove that the identities, sin^-1 cos(sin^-1x)+cos^-1 sin(cos^-1x)=pi/2 , |x|<=1

The value of sin^-1(cos(sin^-1x))+cos^-1(sin(cos^-1x)) where absx le 1 , 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)+(sin A)/(1+cos A)=(2)/(sin A)
