Hey Nishant-small error there:
In the question it already says that 5 appears on one die.AFTER this,we have to calculate the probability,which will be 2/6=1/3.
On the other hand, if the question was "A pair of dice is thrown.What is the probability of getting a sum greater than ten  AND five on one die?",then your solution is perfect..
Cheers!!

Buddy you can use fav.outcomes/tot. outcomes only when each event is equally likely to occur,right?Here I dont think thats the case..

yup...I think thats the only way to do it,right?
all the correct solns i saw were using that itself..
thanks!!

Can someone tell me where to procure AIEEE forms for this year?
Its for my senior and pretty urgent.
I'd be grateful if someone could give me information specific to Bangalore.
Thanks!

2.7% loss is it?
Nice to do profit & loss after suuuch a long time.

even if its an equilateral triangle,how will you do it?

Thanks all !!
Btw polymath,will you give second derivative too?
Thanks

Thanks buddy...I was on the right path after all...
Thanks again

lol!!!
another weird idea i had...thanks spidey & polymath!!
Its pretty clear now!!

Find dy/dx,
where y=a(1-cos)
x=a(-sin)
Kindly give solution also.
Rates assured

where y=((xx)x)x...which goes on till infinity.

Also,is the first derivative = y2/x(1-ylogx) ???

Both of you are correct,but I'm unable to visualise it..if the flag flutters in NE direction,shouldnt wind be in SE direction?It be a great help if someone could explain this with a diagram.
Thanks

No,spidey,its not zero...thats the second part.
@Karthik,I dont think its a projectile(frame of reference not being mentioned),so I'm not sure if you can use g...but your value for x is right.
@rhd...and lokeshsardana..the equation you gave is correct.
My doubt was:dy/dt=wacoswt...how to proceed from there...
I didnt think of integrating-stupid of me.(not to mention I'm not good at it-just learning!!)
Btw,the answers you finally get are:Path:y=asinwx/u.
Distance:sqrt(9pi^2u^2/4w^2+a^2)
Thanks everyone!!

Answer is tan inverse of 1.003,which is approx. 45 degrees SE.I think on simplification,your answer yields the same.

I'm not sure,but I think you take components of velocity that lie along a straight line.

A bobbin with thread wound round it is on a horizontal table and it can roll without sliding.If the end of the thread is pulled with a velocity 'v'  in the horizontal direction,what is the velocity of the axis of the bobbin?
"          "  outer cylinder-R.

In a harbour,wind is blowing at the speed of 72kmph,and the flag on the mast of a boat anchored in the harbour flutters along NE direction.If the boat starts moving with a vel. of 51km towards north,what is the direction of the flag on the mast of the boat?

A particle is moving in a plane with velocity given by:
v=ui+(acost)j.
(i and j are unit vectors along X and Y axes.)
If it is at origin while t=0,calculate trajectory.
At time 3pi/2 find its distance from origin.
(Its quite straightforward,but I'm stuck at one step!!)

I think its 200%
