Is the answer *none*???
Q)For what value of a is following equation true?
lim x->inf ((x+a)/(x-a)) = e

shubhamsrg · Answer

unless a=f(x) .. i dont see any value of a to be satisfying that..

anonymous · Answer

bcuz someone ACTUALLY plugged in (1+(1/x))^x for e value.... i mean, for another question

anonymous · Answer

i looked up similar question online, but it wasn't 
((x+a)/(x-a)) but ((x+a)/(x-a))^x     so when that person plugged in the e value, both sides (^x) cancalled out

anonymous · Answer

it's not *none* right? bcuz that'd b too easy to be true.

shubhamsrg · Answer

i see,,if there is ^x over there,,ans according to me becomes a=1/2 ..

anonymous · Answer

yea! i was wondering if my professor made a typo. cuz this question is way too easy.... a has to be none no matter wat...

sirm3d · Answer

$$\large a=1/2$$

anonymous · Answer

for lim x-> inf ((x+a)/(x-a)) = e ?????????

sirm3d · Answer

if there's no ^x, the limit is 1, not e.

anonymous · Answer

but the question asks:   For what value of a is following equation true

anonymous · Answer

which means without ^x, the limit is 1. which is not 0. which means answer is none right?

sirm3d · Answer

yes.

anonymous · Answer

phewww cool!

sirm3d · Answer

now, if ^x is supposed to be there, the answer to the problem is a=1/2

anonymous · Answer

yay good thing that i had this prob haha
