Midsegment Theorem Proof. The mid segment theorem states that a segment that connects the mid points of any two sides is parallel to the third side and also its measure is half the measure of the third side. That is, DE ll AB and DE = $\frac{1}{2}$ AB. Therefore, CA = CD + DA = 2 CD.
The Prime Number Theorem: The number of primes not exceeding x is asymptotic to x /log x. The Prime Number Theorem: pi(x) ~ x /log x.  a (x) is asymptotic to b (x) and  a (x) ~ b (x) both mean that the limit (as x approaches infinity) of the ratio a (x)/b(x) is 1.
