http://en.wikipedia.org/wiki/United_States The wikipedia says the United States is 3.7 million square miles, for example. So how do you figure out how many miles each side of it is? I'm just using this as an example, is 36 square miles 6 miles a side or 36 miles a side? I think the US is about roughly 3,000 miles wide at the most. The entire earth isn't 3.7 million miles a side. I just don't get it.

find the limit as t approaches 0 of this function: sin^2(3t)/(t^2).
In words, the function is sine squared times 3t divided by t squared. Any help with trig limits and derivatives is also helpful.

What is the limit as x approaches + infinity of (√4x^2-1) / x^2

My book says that if the degree of numerator and denominator are equal, the limit of the rational function is the ratio of the leading coefficients.
I think the limit is (√4) / 1 = 2 am I correct?

f(x)=2x^3 -10x +3 you find the second derivative to determine if it is concave up or down, but I don't know how to find points of inflection. And how would you find the equation of all vertical and horizontal asymptotes?
