RE: Integral in solve on HP 42S?
It is fun (and instructive) to see how concise coding can be accomplished. I'm always fascinated and impressed.
Wondered if the HP 42S could integrate the maximum of (f(x), g(x)) over some interval. Quite easy! For max (sin(x), cos(x)), all that was necessary was to take sin(x), x<>y, cos(x), if x>=y, RTN, x<>y, END I will begin to tryrelearn indirect addressing (last did this on an HP 67 in the 1970's when I programmed a simple baseball game...had lineups and data of 1970 American League teams on the magnetic cards, and used indirect addressing to remember where in the lineup I was at). Then, try to refresh my knowledge on the usage of flags!
