Handheld calculators are now powerful enough to have become indispensible tools for the engineer and scientist. With enhanced equation solving capability and extensive user memory, the HP-28S introduces exciting new possibilities. The entire set of tables for one-dimensional gas dynamics can be accessed with unequalled accuracy and speed. But this enhanced power cannot be properly tapped without a pre-planned user directory organization which takes advantage of the HP-28S internal structure. Experience has shown that many students buy expensive programmable calculators but underuse them, finding their powerfulness baffling and frustrating. They employ the same computational techniques with sophisticated $200 continuous-memory programmable machines as could be accomplished with a simple $20 scientific calculator. This manual contains a compendium of useful formulae, programming, and computational techniques for the popular HP-28S Pocket Calculator. In addition to helpful instructions on units conversion, directory organization, and problem-solving methodology which will benefit any HP-28S user, the Aeronautical Engineering student will find sections on Thermodynamics, Aerodynamics, and Controls which will prove useful in those fields of study.
