anwer will be negative and in fraction you can see easily in the graph of sinx and cosx they intersect at 450
and after that sinx is above then cosx.
Arun
here in f(1), 1 is angle in radian.
so f(1)= cos1βsin1
this will be a negative answer as in [0,
/4) cos will be greater than sin.
and 1 will be less than /4.
