Calculus Beginners Guide to Complex Analysis

Click For Summary
The discussion revolves around the challenges faced in understanding complex numbers and their applications in a course on oscillations and vibrations. The course briefly covered complex numbers, including operations, complex roots, and Cauchy's integration theorem, but the participant found the pace overwhelming and noted the absence of foundational concepts like Euler's identity. There is a strong emphasis on the necessity of complex analysis in physics, prompting the need for beginner-friendly resources. Recommended books include Freitag & Busam for a mathematical approach, Needham's "Visual Complex Analysis" for intuitive understanding, and Boas' "Mathematical Methods for the Physical Sciences" for a balance of rigor and accessibility. Additionally, a free online resource by James Nearing is suggested for further study.

OK, so i took a course named "Oscillations and vibrations"
We began the course with an "introduction" to complex numbers, basically we raced through them in like 3 classes, we talked about how to get complex roots, adding, multiplying, Cauchy-Riemann Conditions, Cauchy's integration Theorem (quite similar to Stokes and Green theorems, at least in their conditions), and today we saw what certain operations do to functions, for example how w=z^2 just transforms it into a kaleidoscope.
Problem is i didn't quite get it, for example the teacher didn't even mention Euler's identity in the slightest, basically i need a book that teaches me, at least, basic complex analysis like a total beginner, i know about Vector analysis but not complex and i kinda need some guidance, I've been told you use complex numbers for everything in physics, so i'll need that guidance.
P.S. it's amazing how real numbers aren't enough o.0 it kinda blew my mind

That's because it can be proven from Stokes' Theorem.

Anyway, my favorite book is Freitag & Busam. But it might be too mathematical for your taste. Needham's Visual complex analysis is a great book with great intuitions. It might be what you're looking for, but it isn't exactly meant to be rigorous. Somewhat in between is Boas "Mathematical Methods for the Physical Sciences". Flanagan's "Complex Variables" is like Boas, but more extensive.

I'm sure one of these books will appeal to you.

Another option (along the same lines as Boas) is the free online math methods book from James Nearing:

http://www.physics.miami.edu/~nearing/mathmethods/

which has two relevant chapters (3 & 14) that may be helpful.

Im currently reading mathematics for physicists by Philippe Dennery and André Krzywicki, and I’m understanding most concepts however I think it would be better for me to get a book on complex analysis or calculus to better understand it so I’m not left looking at an equation for an hour trying to figure out what it means. So here comes the split, do I get a complex analysis book? Or a calculus book? I might be able to Borrow a calculus textbook from my math teacher study that for a bit and...
