Hello
need help with this one.
f:[0,1] --> [0,1]
f( .x1 x2 x3 x4 x5 ...) = .x1 x3 x5 x7
( decimal expansion)
prove that f is nowhere diffrentiable but continuous.
i tried by just picking a point a in [0,1] and the basic definiton of differentiability about that point...doesnt seem to work! kindly help.
