Let `f` be a non-negative function defined on the interval `[0,1]`. If `int_0^xsqrt(1-(f^(prime)(t))^2)dt=int_0^xf(t)dt ,0lt=xlt=1,a n d \ f(0)=0`, then
a. `f((1)/(2))lt(1)/(2) and f((1)/(3)) gt (1)/(3)`
b. `f((1)/(2))gt(1)/(2) and f((1)/(3)) gt (1)/(3)`
c. `f((1)/(2)) lt (1)/(2) and f((1)/(3)) lt (1)/(3)`
d. `f((1)/(2)) gt (1)/(2) and f((1)/(3)) lt (1)/(3)`

A

`f((1)/(2)) lt(1)/(2) and f((1)/(3)) gt (1)/(3)`

B
