फलन `f(x)=1/(2+x) "की" x = 2 ` पर दक्षिण पक्ष ( Right hand limit) तथा वाम पक्ष सीमा ( Left hand limit ) ज्ञात कीजिए ।

Answer» दक्षिण पक्ष सीमा वाम पक्ष सीमा
`I. f(x+h)= 1/(2+(x+h)) " " I. f(x -h)=1/(2+(x-h))`
` II. f(2+h)= 1/(2+(2+h)) " " II.f(2-h)=1/(2+(2-h))`
` =1/(4+h)" "=1/(4-h)`
` III. lim_(h to 0) f(2+h) " " III.lim_(hto 0)f(2 -h)`
` lim_(h to 0) 1/(4 +h) " " lim_( h to 0) 1/(4 -h)`
या `f(2+0)=1/4 " " या f(2-0)=1/4`
