Did I put this in the wrong section? I'd love some help when someone can manage the time. Thanks.

Okay, so I'm working on using spherical harmonics to fit a model to some data. The thing is, everything can apparently be described as a "linear combination of spherical harmonics" but nobody is explaining in plain English what that means, at least to me! :D I see lots of double sum...

I'm using equation 590 as seen on this page: http://farside.ph.utexas.edu/teaching/qmech/lectures/node75.html Thanks again!

Alex, thanks for your response. That makes sense, but then I can't figure out where the complex numbers come into play. If I have pairs of two variables and I know for example that they are coordinates in Cartesian 3D space and real numbers (with another value attached to them which I am...

What, "Physically" is a Spherical Harmonic? I'm trying to use spherical harmonics to get an equation to fit a set of data I have. I'm fine with that, I've found a derivation of what the general form is and I crunch that into MATLAB. My problem is derivations online really don't help me...

Hello everyone, I am a junior Mechanical engineering student with a midterm in my Vibrations I class on Thursday. I've been studying but I'm having some issues really nailing the concepts fundamentally. I feel like I'm stuck in a rut of doing the problem like in the example, but not really...
