A correction in my above post:

Plz correct this step:

{(sin y)/x+(log x)(cos y)(dy/dx)} +( -cos x)/y(dy/dx)+(log y)(cos x)=0

The corrected step is:

{(sin y)/x+(log x)(cos y)(dy/dx)} +( sin x)/y(dy/dx)+(log y)(cos x)=0

Solving by using log will be slightly easy:

Taking log on both sides, you get,

(sin y)( log x) + (sin x)( log y)=0

Now differentiate wrt x,

you will get,

{(sin y)/x+(log x)(cos y)(dy/dx)} +( -cos x)/y(dy/dx)+(log y)(cos x)=0

Simplify this and u'll surely get the answer.

See this if incase u didn't understood.

$put\;\;y\,=\,log_3{x}\\\\y=\frac{log_ex}{log_e3}\\\\Differentiating \,wrt\, x\\\\\frac{dy}{dx}=\frac{1}{log_e3}\frac{d(log_ex)}{dx}\,\,\,\,\,\,\,\,\,\,\,\,since\,\frac{1}{log_e3}\,is\,constant\\\\=\frac{1}{xlog_e3}$

Hope u got it.

article is good but poor presentation and alignment.

I think it should be HIGHER ALGEBRA- By Hall & Knight.
I dont have a link for it but its good for progressions and complex number.

Using your Windows Key:
I didnt found any change effect of Alt+Space+N on my pc.
To minimise a window u must press Wnidow+M and to open it u must press Alt+Tab.

Force may be defined as a push or pull that disturbs or tends to disturb the state of rest or of uniform motion of a body.

In other words, it is a push or pull that disturbs or tends to disturb the inertia of a body.

Force has a formula, F= ma,

where m=> mass of the body and a=> acceleration of the body.

As force is a product of a scalar(mass) and a vector(acceleration) it is a vector quantity.

Units:- CGS----- dyne , SI-----newton(N)

Conversion of newton to dyne: 1N = 10^5 dyne

Dimension: $[M^1L^1T^{-2}]$

Yaar if none of the above books are jee oriented then which book is jee oriented OR tell me which is most jee oriented.

Take a transparent trough full of water and a cardboard on which u can place the 8 coins in succession. Now place the cardboard on the rim of the trough and tilt it so that all the coins enter the water at the same time.
Now, observe the coins.
The coin which reaches the bottom first is the heavier one.
This method can do ur work in first attempt.

Hey in 1. eg. 1 the answer should be 1/h

Plz follow the link below and u will get what u need:

Hey yaar everything is nice but whats this barista etc. in between the article, plz edit it.

Just go to the advanced search option and search books, u'll get all the books which were suggested to goiitians by experts and the community.
Plz dont continue this thread since there have been innumerable past thereads like this one.

Put it in the indian politics way,

''The enemy of their enemy is their FRIEND''
therefore, -ve(enemy) x -ve(enemy) = +ve(friend).

Hope i m understood by u.

Dont u know islamic history.
Even our HOLY PROPHET had suffered this.
If u bear the tortures and taunts of ur classmates, surely ALLAH(The Glorified and The Most High) will reward u.
When HOLY PROPHET used to pass thru the streets of medina a jewish women used to throw garbage on him.
Inspite of this HOLY PROPHET didn't reacted to her action and used to travel thru the same street.
One day the women did not throw the garbage, HOLY PROPHET inquired about the women and came to know that the women is ill.
He went to her, the women thought that MUHAMMAD is coming to take revenge from me and pleaded to him not to do so.
HOLY PROPHET calmed her down and told her that he has come to see her after coming to know abt her illness.
The women seeked forgiveness from the HOLY PROPHET and accepted ISLAM.
