Find the maximum area of a parallelogram drawn in the area enclosed by the curves y=4-x^2 & y=x^2+2x
We will use geogebra! Let's see if we can do this.
1) Type in f(x) = 4 - x^2
2) Type in g(x) = x^2 + 2x
3) Use the intersection tool on the two functions and the points A and B will be created.

Prime Number Theorem
Definition: Pi(x) is number of primes less than or equal to x.
lim(x->infinity) Pi(x)/[x/ln(x)] = 1
Then, obviously for large x, Pi(x) ~ x/ln(x)
This one stumped me.
