24are u guys using LH ???????????
i dont answer by that method then beocz it would be toooo long..........
give some other good method if u have......
11log(1+x)=x-x2/2+x3/3-x4/4.........................
now replace x by x-a-1
and denominator mein x by ex-ea-1
upper niiche kat jayega
and hence ur answer !!!!!!!!!!!!!
106one small doubt.. when x=a- then x-a < 0 therefore log function itself is not defined...
11yup, same contoversy with
\lim_{x\rightarrow 0}\frac{sin\sqrt{x}}{\sqrt{x}}
106more appropriate question shud have been lim(x→a+) i think... btw if this came in JEE then what shud be the answer.. if it was x→a doesn't exist or will it be cos(a) ?
