計劃進修PhD/Research討論區 (11) All money is a matter of belief

話說有冇人就黎搞visa
好驚遲d 中美關係變差搞到侵ban9香港

拎咗I20，約咗星期五搞

Consider f=0 if rational, =1 if irrational

我都係咁諗,不過搵唔到value in(0,1)咪做唔到個conclusion

但係條theorem holds for constant function wo

constant function本身continuous架啦

I mean, 所以攞個value 係inclusive
即係 [f(a), f(b)] assuming f(a)<f(b)

sin(1/x)得唔得

以為係複雜野
