Now revisiting the problem I guess you're right. If there are two terms and you can't find a solution for them as they are, you won't find a solution with their inverses, either. e.g. sin(x)-log(x)=0 If you can't find a solution for this, you won't be able to find one for asin(c)=exp(c). I'm not sure how I got on this track of thinking. Perhaps it was an extension of the idea of finding trivial solutions for the case where some sum of terms = 0 therefore if you can find an x that sets each term to 0 then that's a solution. I must have been thinking that if you could, for two terms, find a value (not necessarily 0) that would cancel the two terms out then you would have a solution as well...but if you can find that value then you should be able to solve the original problem. [hand to forehead] Now the question of symmetry remains. If you have 3**x-x**3 there is a lambert solution of 2.478 which is found by inversion but there is also the solution of x=3...but maybe that is just the other solution from the -1 branch of lambert. Maybe anything that looks like this but is actually something else (sin(x)**.5-.5**sin(x) with solution of x=. 5) is just too esoteric to be of siginificance. /c --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
