HP 30b Programming

[lrdheat]

While the programming of the HP 30b can be a challenge due to some functions being hidden in menu trees, it can be satisfying, and nice to be able to program in RPN mode! With this unit being so pocketable (more so than the 35S), it is nice to have a few programs available at close reach, while at the same time, having a nice number cruncher, good statistics and regression tools. For financial interests, I imagine it would be a nice pocket unit as well. The solve capability is nice as I can use 0 stored in register 2, and a guess of a root in register 1 which will direct the search for root of my programmed function (a non zero constant can be stored in register 2 if one is interested in obtaining f(x) at the given x. It’s not the most friendly programming environment, but I am having some fun!
