| dn4 | anyone here fluent with maxima? |
| tamberlane | Meh, just testing. First, well, second time I've tried it. |
| thermoplyae | It works in pm if you want to tinker |
| tamberlane | Ah. |
| penos | dn4: go and learn it yourself. it's not hard |
| eigenburak | you can spoil him with botsnacks all you want in pm |
| Orange1 | (2x - 5) / 7 == 2x / 7 minus 5/7 ? |
| dn4 | Function: implicit_derivative (f,indvarlist,orderlist,depvar) <-- how would I use this to solve x^2+y^2=1 finding y prime ? |
| diseaser | dn4: 2x + 2yy' = 0, solve for y' ^-- use the chain rule to get that |
| dn4 | well I am wondering how to put the equation into maxima |
| diseaser | oh sorry, I dunno :) |
| dn4 | nor do I hehe |
| diseaser | well depvar is probably y', since it's dependent on everything else the "dependent variable" as y = f(x), y is the dependent variable (dependent on x) i think indvarlist is probably "independent variable list" which could be x & y f = the function orderlist, not sure what that could be. ive never used maxima.. i'm just kind of connecting the dots here |
| The_PHP_Jedi | If I have an applicance on for 8 hrs...consuming 200 Wh (watts/hour)... $0.065 kWh (kilo Watts/hour).... 8x200=1600W... 1600W....1600/1000=1.6 kW... 1.6x0.065=$0.104 for eight hours <-- is that correct??? |
| |Anubis | the derivative of -x is 1 ? or -1 ? |
| tamberlane | -1. |
| |Anubis | k |
| The_PHP_Jedi | Anubis: can you help me? |
| |Anubis | maybe |

| |Anubis | ? you dont need help for that errr, wait |
| The_PHP_Jedi | ok, I'm just asking if my procedure is correct... I'm not sure.. |
| |Anubis | .. |
| The_PHP_Jedi | 10 cents is really low :-\ |
| |Anubis | how many watts/hour 1 |
