thik hai sunil....... but u cud do us rather the community a favour by deleting ur graf posts......

Lokesh Verma ·

yes it will..

then in that case.. can you just draw whatever conclusion is available from here?

wudnt f"(x) bcum a lil tooo long!!! LOL [3]

Lokesh Verma ·

cool :)

good so far.

one more thing.. the second derivative is to be foudn to see the convexity.

and for x<1-e;

function increases till max occurs at this bcoz logs bcum -ve in this interval....

(e+x)^(e+x) = (Î +x)^(Î +x)

then again dec till x>-e

OHKKKK.......

f'(x) = { (pi+x)-1ln(e+x) - (e+x)-1ln(pi+x) } / {[ln(e+x)]2}

denominatr > 0 always......

for x>1-e;
Both the logs are positive......

so numrtr < 0
as (e+x)^(e+x) < (pi+x)^(pi+x)

ther4 cont decrising in da intval 1-e<x<∞

I think you are doing pretty well tapan..

You should now look at the derivative and the nature of the curve near the point (-e+1) on both sides..

Then you can move forward.

Sir, ARe my points correct????

in this question ther is no symmetry......

wat else shud i look 4?? [7]

yup we dont require any apology dear.........kindly remove these graphs from the threads so that others can give an honest attempt to the question....[1]
Hoping that this won't be repeated again[1][1]

Good one.. I will shift this to the graph of the day :)

bhai log...
Sorry......

ab se no such graphs..
Ok.
Accept my apology....

yah...... EUREKA IS SPOT ON!!!!

PL. MATE(SUNIL), U R SPOILIN THE FUN OF DA GRAF............. ITS A CHILD'S PLAY TO GENERATE GRAFS FRM DA COMP..... Y DONT U TRY IT URSELF...... U'LL NOT B ALLOWED UR LAPTOP INTO DA EXAM HALL IN IIT

plzzzzzzzzzzz dont do this yaar.................dont post computer generated graphs.........plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz[2]

Removed! (Nishant)

tapanmast Vora ·

max for the portion in -e<x<(1-Î )
occurs wen

(e+x)^(e+x) = (Î +x)^(Î +x)

ther r no other max/min in da graph

pl. correct me if i'm wrong..... koi javab to do... ?? [7]

tapanmast Vora ·

fol. are some of its char.....

1. functn defined only till x=-e (obviously)

2. y=not defined at x = -e + 1

3. y<0 for (1-Î )<x<(1-e)

more cumin soon..... lol
