1arey ... for objective purpose,,,
put n=0 [since nothing is told about n]
so u get limx->∞ 2/e[x] = 0

1THE FUNDA TO BE USED HERE IS
WHEN x→∞ THEN [x] CAN BE TAKEN AS x
AND IN THE DENOMINATOR USE THE EXPANSION OF ex = 1+x/1!+x2/2! + x3/3!........
CUT IN THE NUMERATOR AND THE DENOMINATOR TO GET UR ANSWER
11yes it would be advantageous to know the expansions
some questions r made 4 them
it is 1 of them
1@sky we just cant substitue directly n as zero as d ans can have n term in limit questions
1no there are two trms : xn = 1 wen n=0 and there is another 1 ..
so 1+1 =2 [3]
waise kya farak parta ?
62ex may or may not be in syllabus...
but it is a must know!
I dont think you need to know any expansion other than ex aand log x
