FYI, this was fixed here: https://github.com/skirpichev/omg In [1]: limit((x + exp(x))/(x - 1), x, -oo) Out[1]: 1 In [2]: limit((ln(x) - 1)**(1 - sqrt(x)), x, E) Out[2]: ∞ On Saturday, April 11, 2015 at 3:22:32 PM UTC+3, Arnaud Usciati wrote: > > Hello, > > I found 2 issues with limit(). > > x =

Hi Gaurav, As of now the solveset doesn't supports assumptions on symbols, and moreover it's still in sandbox mode. Solveset will eventually replace solve by the time it fixes all the mess around old solve. Also, It is very important that the solveset to be tied with the `new` assumption system,

Hi everyone >>> from sympy import * >>> from sympy.solvers.solveset import * >>> a = symbols( 'a' , real=False ) >>> solve( a**2 - 1, a) [] >>> solveset( a**2 - 1, a ) {-1, 1} Should not the output of both solve() and solveset() functions be same ? Is there anything i am doing wrong ? -- You r
