You have some explanation? It simply can't?The manual doesn't say it can or can't from what I can see, but the EL-506A couldn't solve the following while the EL-546 can: 3x + y = 15 x + 2y = 10 EL-506A: Error EL-546: x=4, y=3 Det=5 The way the 3-VLE mode works is you enter the coefficients in sequence: A1 -> B1 -> C1 -> D1 A2 -> B2 -> C2 -> D2 A3 -> B3 -> C3 -> D3 x -> y -> z -> Determinant For the 2-variable linear equation I left C1, C2, A3, B3, C3, D3 all set to zero: 3 -> 1 -> 0 -> 15 1 -> 2 -> 0 -> 10 0 -> 0 -> 0 -> 0 4 -> 3 -> S -> 5 (S = Skipped, the EL-546 skips this since it's a 2 Variable equation) In addition according to the manual for the EL-506A it shouldn't work for equations where D1, D2, and D3 are equal to zero: x - 2y - 3z = 0 3x + 2y - z = 0 3y + z = 0 EL-506A: x=0, y=0, z=0, Det=-16 EL-546: x=0, y=0, z=-0.5, Det=-16 (WRONG) But the EL-506A gives the correct answer anyway, though the EL-546 give a wrong answer back.

That one looks to be a real pain to scan (132 pages with text printed close to the middle). (08-20-2021 01:28 AM)giubin Wrote: EDIT: Your Sharp EL-546 is so fascinating too. I like it.Yeah I'm fond of it too , hopefully you will come across a good deal on it online (they seem to sell for cheaper than the EL-506SLR from what I've seen). In saying that the EL-506A is noticeably faster than the EL-546 and a little bit faster than the EL-506P (maybe they clocked the chip down on the EL-546 so that it could work better off the solar cell?) |
