Markov's inequality states that for any real-valued random variable Y and any positive number a, we have Pr( Y ≥a) ≤ E( Y )/a. One way to prove Chebyshev's inequality is to apply Markov's inequality to the random variable Y = (X − μ) with a = (kσ) : It can also be proved directly using conditional expectation: Chebyshev's inequality then follows by dividing by k σ .

WebD. J. Newman gives a quick proof of the prime number theorem (PNT). The proof is "non-elementary" by virtue of relying on complex analysis, but uses only elementary techniques from a first course in the subject: Cauchy's integral formula, Cauchy's integral theorem and estimates of complex integrals. Here is a brief sketch of this proof.
