# What can I do to find a post I saw earlier today?

Earlier today I saw a post on math.stackexchange regarding why $Ce^x$ is the only solution to $y=y'$. I saw it on my phone and now when I came home I want to study that poster alittle bit more. But I can not find it, what can I do?

• It might be possible to check the browser history on your phone. (Was it a new post or did you just stumble across it?) – quid Nov 17 '16 at 17:54
• I was using the app, dont think there is a history there? I believe I found it just browsing post on math. @quid – Olba12 Nov 17 '16 at 17:55
