HP-9G adding angles Message #1 Posted by Mary on 13 Nov 2004, 2:21 p.m. Does anyone know if the HP-9g can add or subtract andles in degrees minutes and seconds?

Re: HP-9G adding angles Message #2 Posted by Norris on 13 Nov 2004, 2:53 p.m., in response to message #1 by Mary I don't have a 9G, but my guess is that it probably does *not* have built-in functions for adding or subtracting values in degree/minute/second (DMS) format. However, the 9G is programmable, and it should it be easy to create simple programs to add this functionality. The programs simply need to do the following: (1) take two entered values in DMS and convert them to decimal degrees (2) add or subtract the two values, yielding a result in decimal degrees (3) convert the result from decimal degrees to DMS I've used programs of this sort on the 32SII and 33S. The 48GX has this capability built-in.

HP9G learning module for this available Message #3 Posted by Gene on 13 Nov 2004, 3:11 p.m., in response to message #1 by Mary http://www.hp.com/calculators/graphing/9g/technical.html Choose the learning module dealing with Angles and Times from the list. Gene
