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

Dear student
I will recommend you to draw the graph. By this You can check for any angle between sin and cos.
Hope it helps
