I've been teaching myself linear algebra for giggles. I have Strang's Linear Alegra and its Applications and I've been watching his lectures on youtube. I have 3 years of calc behind me (all of Anton's 8th edition). I've also read the first half of Murray Spiegel's Applied Differential Equations. (I stopped after the solution methods by use of series and before systems of ODEs.) What should I study next? I was thinking of doing PDEs, though I'm kind of bored with DEs. I'd be super grateful for a few suggestions =D
Thanks in advance!
