Why do business calculators have log/exp but not basic trig functions?

Note that the 12C and 12CP do not have Trig builtin, but programs have been shared that do provide these capabilities, they are easy to find on this site. On the 12C, I believe they take up most of the available program steps, but on the 12CP there is still some space available for your own programs. What you really want is the HP27SII (adding RPN) but alas, HP never released this one. A real pity. Edit to add: The 17BII+ (Silver) is a great machine, only lacking builtin Trig from your requirements. Again, Trig functions have been written/tested using the builtin Solver feature. The solver language is arcane for very complex use, but for most normal equations, is easy to learn and use. Personal gripe: The 30b and especially the 20b have horrible keyboards, and also frustratingly cramped LCD displays. Too bad, as they're otherwise nice machines. Bob Prosperi
