hi folks, i'm an experienced software engineer wandering into unchartered mathematical territory, and i've set myself a challenge to reverse-engineer the properties of the electron. the referenced PNG http://lkcl.net/moment_formula.png (easiest way to show it) is a screenshot of a formula that i'd like to factorise into the form 1 + a0 * x + a1 * x^2 + a2 * x^3 .... where x needs to be the *specific* value "alpha / (2 * pi)". this allows it to be compared against QED's formula for the electron magnetic moment which, if this formula could be shown to be a potential (accidental) factorisation of the enormously-complex equation from QED would be a really rather large hairy deal.
now, i'm aware that simpy has the ability to expand out equations including sine, exp and to express equations as a power series in x like that but what i _don't_ know is if it can be done where x must be in terms of two (or in this case 3) related constants. first question, then: can simpy do this type of factorisation? second question: if not, what (possibly iterative) approach could be taken to twist scipy's arm into doing the job? if i'm absolutely honest i have no clue where to start here, so could really use some pointers to examples and so on. if anyone _can_ help then i am more than willing to formally give credit in the paper i'm writing up. many thanks, l. p.s. there _is_ a precise mathematical formula (another power series) for alpha-infinity, if that helps at all, not sure if it does but i mention it anyway just in case. p.p.s. hmm let's see if google groups allows images to be put inline into text... it does! ok that may help. <https://lh5.googleusercontent.com/-I-dYeWy5loM/UzAzJoyqYgI/AAAAAAAAALY/OizVd4uiRy4/s1600/moment_formula.png> -- You received this message because you are subscribed to the Google Groups "sympy" group.
