Dear Kanika,

 

 differentiate both sides -

-sinx*f(sinx)* cosx = -cosx

or,  f(sinx) = 1/sinx

put sinx = X

then,  f(X) = 1/X

so, f(1/sqrt.3) = sqrt.3

differentiating  both sides wrt x

 we get

            -cosxsinxf(sinx)=-cosx

                      f(sinx)=1/sinx

                     f(t)=1/t

                      f(1/root3)=root3               ans
