Where Can I Find Information on Fourier Series in 2-D and Orthogonal Systems?

AI Thread Summary
Information on 2-D Fourier Series and Orthogonal Systems is scarce in common texts like Toslov and Butkov's Mathematical Physics and online resources such as MathWorld. A recommended resource for this topic is "Partial Differential Equations and Boundary Value Problems With Applications" by Mark A. Pinsky. Users are encouraged to explore specialized mathematical literature or academic journals for more comprehensive insights. Engaging with online forums or academic communities may also yield additional recommendations. Finding quality material on this subject can be challenging but is achievable with targeted searches.

Hi. I've been trying to find some material about Fourier Series in 2-D, along with 2-D Orthogonal Systems, but i haven't been able to find any about the former in any of the books i have (Toslov and Butkov's Mathematical Physics) nor online (nothing on mathworld?). Any input would be appreciated.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
