    The Algebraic Expression Reserve (AER) memory: Frequently used formulas or constants could be stored in memory and recalled for repeated use. The PC-E500 series also performed as a scientific calculator when switched into 'CAL' mode. It also included an X<>Y exchange key for working with complex numbers and polar to rectangular conversions.

  7. Transcendental equation - Wikipedia

    en.wikipedia.org/wiki/Transcendental_equation

    Graphical solution of sin(x)=ln(x) Approximate numerical solutions to transcendental equations can be found using numerical, analytical approximations, or graphical methods. Numerical methods for solving arbitrary equations are called root-finding algorithms. In some cases, the equation can be well approximated using Taylor series near the zero.
