Evalute (f) (sin36^(@))/(cos54^(@))-(sin54^(@))/(cos36^(@))

The value of ("sin"23^(@)"cos"67^(@)"tan"45^(@)+"cos"23^(@)"sin"67^(@)"cot"45^(@))/(2"sin"45^(@)"cos"45^(@)) is:

Find the value of (sin25^(@))/(cos65^(@))+(tan23^(@))/(cot67^(@))

The expression (sin 22^(@)cos 8^(@)+cos 158^(@) cos 98^(@))/(sin 23^(@) cos 7^(@)+cos 157^(@) cos 97^(@)) when simplified reduces to

The expression (sin 22^(@)cos 8^(@)+cos 158^(@) cos 98^(@))/(sin 23^(@) cos 7^(@)+cos 157^(@) cos 97^(@)) when simplified reduces to

sin36^(@)+cos36^(@)=sqrt(2)cos9^(@)

sin9^(@)+cos9^(@)=sqrt(2)sin54^(@)

The value of (sin22^(@)cos8^(@)+cos158^(@)cos98^(@))/(sin23^(@)cos7^(@)+cos157^(@)cos97^(@))

The value of (sin22^(@)cos8^(@)+cos158^(@)cos98^(@))/(sin23^(@)cos7^(@)+cos157^(@)cos97^(@))
