I'm having a hard time preparing the HP 33s for the Civil PE exam in April. I'm hoping to get some help...
The PE exam involves perhaps hundreds of possible formulas, maybe not all of which will be used on a given exam, but I'd like to be prepared.
HP's SOLVE feature is fantastic for solving equations, but I have yet found no way to index the equations, i.e. I will have to scroll through a long list of equations until I find the one I want, then press SOLVE and the variable name I'd like to solve for. With hundreds of equations, the scrolling could take a long time, and speed is key at the exam.
So, I've looked into programming an index structure, using one routine (label A) to ask for a "subject" and "equation" number (i.e. an index), and then directing the program using the GTO (label) command to other labeled routines that I would like to contain all the equations for the subject covered by that routine.
But, I'm having a hell of a time finding a way to have more than one equation within a routine AND at the same time solving any one of those equations for any specified variable...
HP's examples in the manual seem to suggest you can have only one equation per program. Any ideas??
