SUMMARY

The discussion focuses on identifying the weight functions for Trigg's, Legendre's, Legendre's Associated, and Bessel's equations within the context of Sturm-Liouville theory. The weight function, denoted as ω(x), is crucial for establishing orthogonality and magnitudes of functions through the inner product defined as = ∫ dx.g(x)f(x)ω(x). Participants emphasize that by expressing the differential equations in the appropriate Sturm-Liouville form, the weight functions can be determined effectively.

Homework Statement



Find the weight functions for Trigg's, Legendre's, Legendre's Associated, and Bessel's equations.


Homework Equations



Not sure.


The Attempt at a Solution



I know that the weight function, [tex]\omega(x)[/tex], is real and correlates to the scalar product of functions.

Thanks.
 
Physics news on Phys.org
the weight function determines how functions are othogonal & magnitudes by defining the inner product:

[tex]<f(x),g(x)> = \int dx.g(x)f(x)w(x)[/tex]

if i remember correctly, by writing the DE in the correct SL form, the weight functio nshoudl be reasonably apparent
