67. semester over p2

So in my partial differential equations class, we mainly studied the heat equation, the wave equation, and then we also studied the Laplace equation.

And I suppose before I start talking about these equations, I want to talk about maybe some resources.

so i studied my the textbook my school uses is like the walter a strauss textbook which i didn't read a lot i think it's hard to read textbooks while you're in the class depending on the textbook um i feel like i feel like mainly math textbooks are hard to read sometimes when when they're in the class sometimes i don't know um this one was at least there's also another one like haberman that i think i read very little I think it might be good for engineering or for understanding stuff.

Um, yeah, I'm not sure that I was able to solve stuff with, with the Walter Strauss one, but it's, it is more physics.

I think, or I'm not sure it tries to be, um, more natural science based, I think.

And it has, it has some stuff that is, Yeah, I'm not even sure how to answer that actually.

I haven't looked at this textbook a lot.

But the Haberman one is good.

My professor was saying that it was good too.

Another textbook that I think might be good to look at is the Boyce de Prima one.

And I think that one is because I'm looking at it now in retrospect.

This was my textbook last semester.

I didn't use it a lot.

And I think it had decent problems.

The problems were nicely formatted, I think.

comparatively to Walter A. Strass one.

Nicely formatted to see which ones should go faster, which ones are more computational, and which ones are not as computational, or more like theory, or more think, or more different stuff, right? But the Boise Primo one is mainly for ODEs, and then it has some PDE stuff, I think, towards the end.

I'm not sure how much it is actually used for PDEs, but it has some chapters towards the end, and I'm re-reading this or I'm trying to read this textbook for the first time or finish it and solve all the problems.

Um, but, um, yeah, I think it explains stuff fairly decently in retrospect, or it has some interesting like ideas and, and that are piquing my interest.

And, and so, yeah, actually I feel like this book is, is, is, is good.

Hopefully I find another one for, for PDEs better, but, um, But that's what researchers I suggest you go to.

Yeah.

So I guess now let's talk about the heat equation, the wave equation, and and Laplace, which actually I don't even think I know that much about the Laplace.

Maybe I'll talk about that one later, but I'll probably stick to heat and wave mainly here and mention some other like theory stuff that I thought was kind of cool.
