Not able to solve a system
Hello,
I'm trying to solve the following system using SolveSys: (X/Y)^Z = 1/8 2^X/3^Y=4/Z^4 X*Y/Z=8/3 On the HP50g, I just use the equation writer to place all 3 equations on the stack, then create an array with them. I then create an array with [X Y Z] and another with my initial guesses [1 1 1]. I go to NUM.SLV-->MSLV and then get an array with 2, 4 and 3 as the answers. However, when trying to solve this system on the Prime using SolveSys, I get the following message: Newton iterations terminated but ||F|| failed tolerance The (incorrect) answers that I get are X=1.505 Y=4.984 Z=2.759 What am I doing wrong? |
