20161103 10:56:03 +0100  commented question  Numerical real solution of derivative The same issue persists  changing the variable x to 2x shouldn't make a difference, but it does. This might not even be an issue with precision, very weird. 
20161103 10:45:59 +0100  commented answer  Numerical real solution of derivative Thanks for your help again, I've again updated my answer. It seems that 2*x and x makes all the difference for Sage. The solution should be some x around 0.01.

20161103 08:58:31 +0100  asked a question  Numerical real solution of derivative I would like to know where a function attains its maximum, so I'm trying to solve some
where y depends on y. I have difficulties with Sage returning equations, complex roots, converting equations, find_maximum_on_interval command etc, and instead of spending another hour trying to figure it out myself, I thought I would try asking here... Here is a more concrete example:
What is mysterious for me, is that the above works if instead I have
