सिद्ध करें की `tan 62^@=(cos 17^@+sin 17^@)/(cos 17^@ - sin 17^@)`

(cos17^(@)+sin17^(@))/(cos17^(@)-sin17^(@))=?

(cos17+sin17)/(cos17-sin17)

( cos 17^(@) + sin 17^(@))/( cos 17^(@) - sin 17^(@)) = tan 62^(@)

(cos 17^(@) + sin 17^(@))/(cos 17^(@) - sin 17^(@))= ................ A) tan 62^(@) B) tan 56^(@) C) tan 54^(@) D) tan73^(@)

sin47^(@)+cos77^(@)=cos17^(@)

(sin19^(@))/(cos71^(@))+(cos73^(@))/(sin17^(@))

What is the value of (sin 19^@)/(cos 71^@) + (cos 73^@)/(sin 17^@) ?

Prove that: sin 47^0+cos 77^0=cos 17^0

Evaluate :- (sin^2 63^@+sin^2 27^@)/(cos^2 17^@+cos^2 73^@) .
