對手係小學生時: 你唔識ga 啦 算吧啦
對手係初中生時: 1/9= 0.1111111..... => 0.111111....*9 = 0.999.......= 1/9*9=1
對手係ce考生時: set x lim x->1
對手係al 考生時: as 0.9999 is very near to 1, let's assume it=1 \ / |
that's just cuz the error will be unlimitedly small...
0.9999...... is unlimitedly close to 1, but can never be equil to 1.
you can
assume it to be 1 because like i said earlier, the error will be unlimitedly small, so the result will be basically the same.
so in conclusion...as an ammount, it is unlimitedly close to 1, but as in calculation....just assume it to be one...cuz the answer won't really make a difference anyways..../
