Yeah, I was just given the formula you specified...

I did do the same thing, but the answer is not consistent with the solution given.. For a) the solution given is 0.9961...

Hi.. This is a question I found in a text that I am unable to solve.. Help would be appreciated..
"Because not all airline passengers show up for their reservation, an airline sells 125 tickets for...

You should start by getting the expression in the form of 't= (.. )' once u have reduced the expression , it is just normal diffrentiation wrt x. Try doing it.. u may need to use logarithms to get...

I think thr is some error in your ans.. for x=1/2, the only value for y is -13/12..

Proceed according to the following steps:
1. Find a relation between radius(r) and height(h) of the cone.
2. Substitute for 'r' in terms of 'h'in the volume equation of the cone.
3. Find...

Thanks a lot.. one more question, if I need to find the normal to a given unit vector, how do I go about it..

If I have 2 vectors A and B in 3D,how do I find the normal component and parallel component of one on another??

The notation given by jerry is exactly right.. The answer given is 5/3... I don't know how to arrive at it..

how do u find the value of 'sigma' from n=-infinity to infinity for (1/2)^(2 mod n)..
sorry wasn't able to put it in the right format..

Sure:-):-)

This wasn't an assignment.. I just came across it in a book, so I thought of working it out.. thats it..

the factor of 9 can be accounted for if u consider that Q is distributed among 3 spheres equally.. this implies that value of 'q'is Q^2/9 rite..

[/QUOTE]

it can further be reduced to -1/sin(x) =-csc(x)
{2 sinAcosA = sin 2A}

Thanks a lot...

d^2(z)/ dt^2 = 0
How do we integrate this twice?
Please give me the steps of working too..

It is a spot deviod of photoreceptors(rods and cones).It is this point where the optic nerves exit the eye and moves towards the brain.

Thank u.. I got the solutuion..
