Limes i algebarske operacije

Neka su \(f\) i \(g\) bilo koje dvije funkcije koje imaju limes u točki \(a\). Uvedimo oznake:

\[\color{red}{\large{\underset{x\rightarrow a}{\lim }f\left( x\right) =L,~\ \ \ \ \ \ \underset{%
x\rightarrow a}{\lim }g\left( x\right) =M}}\]

Tada vrijede pravila:

\(\color{green}{Limes\:zbroja\:i\:razlike}\)

\[\color{red}{\large{\underset{x\rightarrow a}{\lim }\left[ f\left( x\right) \pm g\left( x\right)\right] =L\pm M=\underset{x\rightarrow a}{\lim }f\left( x\right) \pm \underset{x\rightarrow a}{\lim }g\left( x\right) \tag{LP1}}}\]

\(\color{green}{Limes\:umnoška}\)

\[\color{red}{\large{\underset{x\rightarrow a}{\lim }\left[ f\left( x\right) \cdot g\left(x\right) \right] =L\cdot M=\left( \underset{x\rightarrow a}{\lim }f\left(x\right) \right) \cdot \left( \underset{x\rightarrow a}{\lim }g\left(x\right) \right) \tag{LP2}}}\]

\(\color{green}{Limes\:i\:konstanta-Posljedica \:LP2}\)

\[\color{red}{\large{\underset{x\rightarrow a}{\lim }cf\left( x\right) =c\underset{x\rightarrow a} {\lim }f\left( x\right) \tag{LP3}}}\]

\(\color{green}{Limes\:kvocijenta}\)

\[\color{red}{\large{\underset{x\rightarrow a}{\lim }\dfrac{f\left( x\right) }{g\left( x\right) }=\dfrac{L}{M}=\dfrac{\underset{x\rightarrow a}{\lim }f\left( x\right) }{\underset{x\rightarrow a}{\lim }g\left( x\right) };~\ \ \ \ M=\underset{x\rightarrow a}{\lim}g\left( x\right) \neq 0 \tag{LP4}}}\]
