Hello, I have purchased the HP50g and am liking it so far. However, I find the manual and online references lacking in particular areas. For example... 1) How do I load a program into the calculator and then access it? I am able to use Conn4x and connect to my calculator. But then all I get is a list of files and a folder of more files. The particular program I want to load is a periodic table. I dont know where to put the file, nor do I know how to access it once in the calculator. The readme for the program says this 2.1 Installing -------------- a) send either chemlb27.lib(full) or chemlt27.lib(light) to the HP48 b) put a copy of the library on the stack c) enter the port number to store the library (0-33 GX, 0-2 SX) d) here is an example of the stack setup so far: -------------------------- 4: 3: 2: Library 1014: CHE... 1: 0 | | | | | | | e) at this point, press [STO] f) perform a warmstart with [ON][C] or turn on and off the HP48 g) erase the variable containing the library. eg. 'CHEMLB27.LIB' PURGE h) read the next section for the Universal Font Library (UFL) requirements For part a, I dont know where exactly I need to send it. Part b, what does that mean, 'put a library in the stack'? I am pretty much lost after that... 2)Any tips on how to do symbolic integration? The integral button seems to only do definite integrals. I am having a feeling that this calculator is not good at doing symbolic calculus.... If that is the case I am sure sorry I purchased it... 3)Finally if you have any tips/tricks or useful programs for the calculator pleases share! I want to learn how to use this thing real well over spring break.
