Science & Mathematics - 14 February 2007

I'm suposed to evaluate the limit.

lim(h)-->0 ((sqrt(1+h)-1) / h

I keep multiplying by the conjugate of the numerator, (conjugate/conjugate) ,
but then the denominatore becomes h*sqrt(1+h) + h


Like this:

h+2
--------
h*sqrt(1+h) + h

So I still have a denominator aproaching 0 and I can't cancel anything.

The original equations numerator does not factor.

How do I find the maximum of f(x)=(4x^3)-(99.06x^2)+603.2246x
Please tell me how to solve this algebraically(not with differential calculus nor graphically)
I would greatly appreciate it if you showed me the process step by step. Thank u so much =)

In the future, there will be a usage of cold fusion generators.
Colliders that span for thousands of kilometers made out of platinum and liquid metal.
WHY? B/c I will teach the world why the electron pairs up into mu- and tau- neutrinos byproducts, with increasing mass. And now, at age 20 I have discovered the answer. The answer to the emptiness within the atom. The universe before the big bang. The anti-elementals. Science shall re-create the big bang. Do you know what will happen???

I have:

F(x)= S(sqrt(2t^2+1)) on the interval [2, x].

Now, say I want to take the derivative of this. What do I have to tag on to sqrt(2t^2+1) to make it right? Why?

peoples opinions on this subject.

what is the biologicaly superior skin color and why do you say that.

personally i believe darker skin has a biological advantage. because light skin is designed for being in a cold climate with little sunlight and is ment to absorb as much vitamin D from sunlight as it can and burn easily. and with the world having more warm sunny climates than cold dark arctic climates dark skin that is meant to prevent or atleast lessen sun burns and not absorb as much D all at once is better. if a very fair skinned person lived in the carribian where there is constant sunlight and a warm to hot climate they without high spf sunblock over time could absorbe fatal amounts of D and get frequent burns increasing the risk of cancer. but a darker skinned person living in the arctic would have a difficult but not nearly as bad life. just being out in what sun they can be in and dressing warm would suffice.
