Def:(1){Xn}is said to be bounded above iff there is
M屬於R such that Xn<=M for all n屬於N
(2){Xn}is said to be bounded above iff there is
m屬於R such that Xn>=m for all n屬於N
(3){Xn}is said to be bounded iff it is bounded both
above and below.
Srppose that Xn屬於R
: Prove that {Xn}is bounded iff there is a C>0 such that |Xn|<=C
: for all n屬於N(自然數)
以上是補充定義的部份!!
謝謝大家!!
