just a quick ask for recommendations:
I'm a lonely math enthusiast, and my current knowledge goes to a half "mastery" of Calculus 1-3. And a bit of L.A. and discrete mathematics at that. And I've mainly used resources such as Khan Academy and various textbooks that I've come across:
Doesn't matter if it's books, videos or whatever if you're wondering.
More specific: Differtial Equations (Preferably in higher dimensions) and's applications would be of greatest interest. Don't really know to much about it, but just somewhere to start.
Also, google play... Is it any point in looking there? It's the most convenient way if there's a paywall.
Sorry for a kind of long text, but I'd appreciate any help :-). Should you have another course, just say it. Someone else may have use for it...
Thanks in advance
