The function y(x) is given by

y(x)=summation(n=0 to infinity) [x^(2n)]/(1-2n)

a) find the radius of convergence for this power series

b) show that y satisfies the differential equation
(1-x^2) y''(x) - 2xy'(x) + 2y(x)=0

Just to let you know this was my first time and not many of the nurses wanted to stick me with the needle because my veins are small. One nurse ended up getting the needle into my vein after three attempts and from then on out was fine. Afterwards, though, my arm felt a little weird like my vein was being tugged a lot or it just felt very awkward. I just want to know if this is normal because I would love to give blood again.

If I had a 2D shape like a star bent from a single length of wire, how could I 'electrify' it - i.e. pass an electric current through it? I assume that I can't just join the ends straight to the 1.5v battery.
I am trying to create a magnetic field and wonder what shape it would have. Would it matter if the wire touched itself as it kept crossing over itself?

OK, so I really have no idea on this...

I know it is possible to take cuttings from a fruit tree that displays the largest and healthiest fruit in the orchard and plant these cuttings to grow new trees, genetically identical to the tree from which the original cuttings were taken. This could result in an orchard full of superior fruit-producing trees, each maximizing quality and quantity of yield.

However,

What are the short-term AND long-term effects of this approach to this methodology.

THANKS!...

1) I am always 9 million km of fire.
2) When I am old I expand & get Red, I get red for 4 million years only unlike my smaller cousins.
3) After 4 million years I blow up & my light can be seen even after millions of years.
4) But after that I shrink to a small size of 10 km.
5) I suck the life out of the other stars.
6) Astronomers in the Latins have named me " AstroToro" meaning the "StarEater." Not even light can escape me.





Going out should I wear sliver or black gloves?

ok, I can pretty much use any type of material. However, i cannot use parachutes or balloons, anything liek that. the shape in the end must be a common 3d shape like a sphere, cube, rectangle, cone, pyramid.....
ok, we can use anything but cannot glue anything to the egg. we can layer it with anything. Our grade depends on the size of the container. The size of a can of soda is an A, the bigger the lower the grade. anybody know?
