Vector Arithmetic on the Casio fx-991CW
Before you go into a laughing spell, have a look at this.
I decided on a challenge. How do I perform Vector Arithmetic on the CW. Beginning with the example from the HP-21 manual, I just had to give it a go. Fishing around to see the idiosyncrasies the entry and result characteristics of how the Casios work with Rectangular/Polar coordinates and the number entry in each format, a+bi and r∠θ. After a few ideas and tests with the HP-21 example, I successfully devised a methodology. Here’s the MS Word file describing the process. From the looks of the procedure, it could easily be adjusted for the 115 and 991 series. One more reason I don’t need to use the CW as a doorstop or paperweight. Besides, I spent good money on it, so I should give it a chance to prove itself. HP-21 Vector Arithmetic for fx-991CW |
