Dear student 
Just put the value of A and find the value of CosA and SinA , the value which is bigger will give you the result. 
Generally between 0 to 45 degree , Cos A will be greater and from  45degree to 90 degree Sin A will be greater.
You can also check by drawing graph.
Hope this helps 
Good Luck
