Question

please solve limit class 12th​

Answer 1

Here it's very to understand the concept.......

fractional part of any no. always tends to 1

as like,,7.1=7+1/10

here fractional part of 7 is 1/10....which will tend to 1

Other example we can take as8.8=8+8/10

fractional part of 8 is 8/10 ,which is also trending to 1

using this concept we can say

Limit of {x}=1

so,now simply put this in given terms

lim(x->I-){e^{x}-{x}-1}/{x}^2={e^1-1-1}/1^2

=(e-2)

Hence e-2 will be the required limit....

so, option b is the correct one
