Rank: Newbie Groups: Registered Joined: 31/10/2012(UTC) Posts: 4		I solved this equation: http://www.fotosik.pl/po...ek/25a04e7a09ca7cc1.html using WolframAlpha (y is approximately equal 1,69) and then I tried to solve the same equation using last version of SmathStudio (0.95.4594) by means of function "solve" I know that function "solve" acts only in real numbers (in addition, I have arranged a maximum range of roots in Smath (from -1000 to +1000)) and I get a message "no real roots"... Why? Edited by user 05 November 2012 18:53:00(UTC) \| Reason: Not specified

Why? Hi loitzl9006, functions solve(2) and solve(4) works for me, both with standard or custom range (see the attachments) there may be an error in your function? regards, w3b5urf3r File Attachment(s): eq.sm (5kb) downloaded 15 time(s).
