" Q."1quad cos9^(@)-sin9^(@)=

cos 9^(@) - sin 9^(@)=

If the value of cos9^(@)-sin9^(@)=sqrt(2)sin alpha where a in[0,3 pi], then the value of 'alpha' can be -

Prove that (cos9^(@)+sin9^(@))/(cos9^(@)-sin9^(@))=cot36^(@)

(cos9^(@)+sin9^(@))/(cos9^(@)-sin9^(@))=tan54^(@)

(cos9^(@)+sin9^(@))/(cos9^(@)-sin9^(@))=?

(cos9^(@) + sin 9^(@))/(cos9^(@) - sin9^(@))=

Prove : (cos 9^(@) +sin9^(@))/(cos9^(@) - sin9^(@)) = tan54^(@)

(cos9^(@)+sin9^(@))/(cos9^(@)-sin9^(@))=(a)tan54^(@)(b)tan36^(@)(d) None of these (c)tan18^(@)

The value of (cos 9^(@) +sin 9^(@))/(cos 9^(@) -sin 9^(@)) is equal to-

(cos 9^(@) +sin 9^(@))/(cos 9^(@) -sin 9^(@)) is equal to :
