Limit(စည္းသတ္တန္ဖိုး)

  
................x ၏ခ်ည္းကပ္တန္ဖိုး x'တြင္ f(x) ၏စည္းသတ္တန္ဖိုးဆိုသည္မွာခ်ည္းကပ္တန္ဖိုး(x')၏မီွခ်က္တန္ဖိုး f(x') ပင္ျဖစ္သည္။

သေကၤတအားျဖင့္

..............................lim f(x)=f(x') ျဖစ္ပါသည္။

.............................x->x'

Example.1

lim 3x

x->2

Let f(x)=3x

x=4,f(4)=12

x=3,f(3)=9

x=2.5,f(2.5)=7.5

x=2.25,f(2.25)=6.75

x=2.01,f(2.01)=6.03

x=2.001,f(2.001)=6.003

:

:

:

and so on

x->2 => f(x)->6

Therefore

..........lim 3x=6

.........x->2

Example.2

..........lim 5=?

x->3

x=5, f(5)=5…

x=4, f(4)=5

x=3.5, f(3.5)=5

x=3.01, f(3.01)=5

:

:

:

and so on

x->3 => f(x)=5

Therefore,

lim 5=5

x->3

Identity

lim C=C

x->k

proof

lim C=lim C.f(x)=C.f(k)=C [f(x)=f(k)=1]

x->k x->k

[In above example 2,f(x)=C]

မွတ္စရာ

အနတၱမို႔၊စကားခ်ိဳ႕တဲ့၊ခႊင့္လႊတ္ကြဲ႔။

ေလ့လာမွတ္သား၊သုတမ်ားတာ၊မမွားပါ။

ဆိုးသြမ္းမိုက္မဲ၊ပညာနဲရူး၊မေကာင္းဘူး။

မိမိလြန္က၊ရွက္ေနာင္တနဲ႔၊ေတာင္းပန္လွည့္။

ကိုယ့္ရွိပိုလာ၊ေစတနာျဖင့္၊လွဴဒါန္းရွင့္။

ေခါင္းေလာင္းသံညံ၊ကမၺည္းခ်န္မွ၊လွဴဟုတ္စ။

စာက်က္ပ်င္းေန၊အေတြးေတြေခါင္၊သီလေၾကာင္။

မေကၽြးယင္ေဟာင္၊ေကၽြးယင္ေဆာင္တာ၊ေခြးေတြပါ။

အရွက္အေၾကာက္၊ငယ္ထိပ္ေပါက္လွည့္၊၀တ္စားကြယ့္။
