theorem Th7:
  f is_uniformly_continuous_on X implies f is_continuous_on X
proof
  assume
A1: f is_uniformly_continuous_on X;
A2: now
    let x0;
    let r be Real;
    assume that
A3: x0 in X and
A4: 0<r;
    consider s be Real such that
A5: 0<s and
A6: for x1,x2 st x1 in X & x2 in X & ||.x1 -x2.|| < s holds ||.f/.x1 -
    f /.x2.||< r by A1,A4;
    take s;
    thus 0<s by A5;
    let x1;
    assume x1 in X & ||.x1-x0.|| < s;
    hence ||.f/.x1 - f/.x0.|| < r by A3,A6;
  end;
  X c= dom f by A1;
  hence thesis by A2,NFCONT_1:19;
end;
