MATH HELP NOW

[Jf Thunder]

plzzz help, so i can post more questions

 

[jarves]

Just differentiate it and find the stationary point,What is the big deal here??
Now dont say to me that you dont know how to differentiate functions.

dude, i am unable to prove it

dude, i am unable to prove it

Find the x coordinate and put it in the equation and Bingo!!

@JFThunder-Blunder Have you been able to differentiate it or not??

 

[Jf Thunder]

@JFThunder-Blunder Have you been able to differentiate it or not??

i did, it became
-(lnx/(x+1)^2)+(1/(x^2+x))

 

[jarves]

i did, it became
-(lnx/(x+1)^2)+(1/(x^2+x))

What is the meaning of this sign??

 

[Jf Thunder]

What is the meaning of this sign??

raised to the power of like 2 squared would mean 2^2

I have solved the question,In this case you cant find stationary point but you can still prove what has been asked in the question.

gimme picture, not of yourself, pic of the question

Let A= (x+1)-xlnx
B=(x+1)^2 *x

After differentiating you will get this.......
A/B
Equate this to o.
Which means A=0
(x+1)-xlnx=0
(x+1)=xlnx
(x+1)/lnx=x
Proved.

Sorry to say but Your Maths is damn weak.

@JFThunder

wait how did u get A?
and yes my math is shit

 

[jarves]

and yes my math is shit

A is the numerator.Take L.C.M. and make it all one term.I typed fast and made some mistakes in last steps.See my post again.
