There is the famous Mach number equation from the HP-67/97 manual:

\[\sqrt{ 5 \left [ \left ( \left \{ \Bigg [ \Bigg ( 1 + 0.2 \left [ \frac{350}{661.5} \right ]^{2} \Bigg )^{3.5} - 1 \Bigg ] \Bigg [ 1 -\left ( 6.875 \times 10^{-6} \right ) 25,500 \Bigg ] ^{-5.2656}\right \} + 1 \right )^{0.286} -1 \right ]}\]
