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

Evaluate the following: (i) (cos37^(@))/(sin53^(@))(ii)(sin41^(@))/(cos49^(@))(iii)(tan54^(@))/(cot36^(@))

Evaluate the following: (i) sin39^0-cos51^0 (ii) cos e c25^0-sec65^0 +cot34^0-tan56^0 (iii) (sin36^0)/(cos54^0)-(sin54^0)/(cos36^0) +cos^2 13^0-sin^2 77^0

Prove that (sin36^(@))/(cos54^(@))+(cos36^(@))/(sin54^(@))=2

Evaluate the following: sin39^0-cos51^0 (ii) cos e c25^0-sec65^0 cot34^0-tan56^0 (iv) (sin36^0)/(cos54^0)-(sin54^0)/(cos36^0) cos^2 13^0-sin^2 77^0

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

cos54^(@)cos36^(@)-sin54^(@)sin36^(@)=0

Evaluate the following: (cos37^(0))/(sin53^(0))( ii) (tan54^(@))/(cot36^(@)) (iv) (cos ec34^(0))/(sec56^(@))

cos(36^(@)-A)cos(36^(@)+A)+cos(54^(@)+A)cos(54^(@)-A)=
