math - How to manipulate mathematical symbols? -



math - How to manipulate mathematical symbols? -

this more of "educational" question. :)

although, eventually.

so, let's got equation. kind of equation, long it's not ridiculous , human @ math, solve it.

let's say... 0 = (x-1)(x+2)

or... y = (x^2), y = 1/x

or sine functions, etc. basically, doing math did in school.

the question is, how write computer programme solve this? know it's possible, because programs mathematica, maple, etc, have been doing decades! can't find documentation on how create simple equation solver.

i don't expect answers tell me "this how it" because of course of study such thing entire big program, not code snippet.

but general overview, or links documents? great! :)

especially kind of info structures , algorithms needed.

failing that, i'll have figure out how solve equations, , encode that. takes literally months right (i've done sort of thing before, formalising own thinking process code, works it's slow).

have @ papers on symbolic manipulation.

peter norvig's paip book covers simple scheme symbolic manipulation , solving of equations, that'd worth read. introduces basics of ai programme called macsyma formed basis of mathematica.

iphone - Dismissing a UIAlertView - i set in app purchase app, , when user taps button, purchase started. basically, tap button, , depending on speed on net connection, waiting 10 seconds until new alert view comes asking if purchase product. user tap button multiple times since nil came up, , multiple purchase alert views come up. additionally, maybe seen user app bug. in end, problem. i want alert view come spinning wheel says "loading..." when users taps purchase button. problem is, how dismiss when new alert view comes asking user if want purchase product? if ([uialertview alloc] says: @"whatever apple's alert view says") { //dismiss "loading..." alert view here } i uncertainty work, input appreciated. thanks! you need have access alertview. can this. create alertview instance var in app delegate , when want show loading initialize instance var assign property , when want dismiss phone call [alertviewinstance d...

intellij idea - Update external libraries with intelij and java -

intellij idea - Update external libraries with intelij and java - simple plenty really. i'm using apache jars, i'll create changes jar's every often. these jars listed external libs in intelij (i.e classpath looking install dir of jar's). when create changes intelij doesn't seem know new implementation. have remove jar external library , re-ad it. does know have intelij picks changes automatically ? i've done clean , rebuild project had little effect. you can go preferences -> build, execution, deployment -> build tools -> maven -> importing , check box says import maven projects automatically . in mac, can command + shift + a , come in action reimport , click on reimport maven projects . intellij-idea
