  1. Although testing can determine the correctness of software under the assumption of some specific hypothese
  • conditions but can only establish that it does not function properly under specific conditions.

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

\(\cos (2\theta) = \cos^2 \theta - \sin^2 \theta\)

\(\lim_{x \to \infty} \exp(-x) = 0\)

\(k_{n+1} = n^2 + k_n^2 - k_{n-1}\)


f(n) = n^5 + 4n^2 + 2 |_{n=17}
