a. doubled
b. tripled
c. quadrupled
d. halved
e. none of these

Let P_n be a sequence of polynomials of degree <= m (m constant) defined on the complex plane and with complex coefficients. Suppose there are pairwise distinct complexes z_0, z_1,....z_m for which P_n converges. Show that P_n converges on the whole complex plane to a polynomial P whose coefficients are the limits of the sequences of corresponding coefficients of the polynomials P_n.

Now, suppose P_n is as previously mentioned but degree(P_n) is an unbounded sequence. Suppose the sequences formed by the coefficients of same degree of the P_n's converge on C. The limits of such sequences define a function P given by a power series which converges in the interior of some circle of C. Is it true that P_n --> P?

Thank you!

I only need help with the first part cos i can't figure it out

A right circular cylinder is to be made such that the sum of its radius and height is 6m. Find the max volume of the cylinder.

So all i know is: a rt. circular cylinder is a cylinder whose base is perpendicular to its sides.
r+h =6m
V=pie r sq. h, having 3 variables, i have to find a variable using r+h=6m. i need help finding this variable, i know how to work out the rest.

I have noticed that the Second Child of a muliple child family is usually bigger than the first.

So, does the original fetus become a template for next? And does the next grow larger because the womans body already understands the hormonal changes? Programmed?

Have a look around,...2nd borns are usually larger than 1st borns and this even spans gender separation within families.

I think that term had been used in reference to a "Weibull Distribution". Has to do with failure rate over time of some hard drives.

1 thing i have wondered
sure the blind can experience the other effects of the drug
but what do the blind SEE(im talking blind from birth, NEVER had sight) when taking acid or mushrooms or other drugs that cause visual hallucinations
is this something that people with sight will ever even know? (well, until brain reading tech is available)
it would be like explaining color to the blind...but in reverse
