Computer saved by bicycle
Yesterday, I finally managed to convince my neigbour to try wxMaxima, the free Math software that does all the tedious calculations for you and let you worry about what to feed it. The outcome of my neighbour trying the software was not entirely successful. For him that is, for me it was a commercial success. He ended up so frustrated that he threw his new netbook out of the open window where it was saved by the basket of my parked bicycle.
The problem below is what led to the frustration. It seemed to be straight forward, but involving a lot of tedious calculations, which is our weakness and wxMaxima’s forte. The sad thing was that the software found two solutions for BD when we were convinced that only one could exist. When my neighbour asked wxMaxima to check its two solutions it said both of them were correct. That is when the netbook went out of the window.
If you know why the software behaved like it did, please post a comment, but don’t tell my neighbour. I would like to keep his netbook.
