Discussion Overview

The discussion revolves around obtaining a set of orthogonal polynomials up to the 7th term, with a focus on the methods and challenges involved in the calculation. Participants explore the use of recursion relations and the Gram-Schmidt process, while addressing the complexity of integration involved in the process.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant expresses uncertainty about their progress in obtaining orthogonal polynomials, indicating they have reached the 6th term but find the integration increasingly complex.
  • Another participant requests the recursion relation to be provided in LaTeX format, suggesting a preference for clearer mathematical communication.
  • A different participant criticizes the use of hand-written figures, implying that a more formal presentation in LaTeX is necessary for effective discussion.
  • Some participants suggest that the original poster may be working with Legendre polynomials, referencing external resources for verification.
  • There is a question raised about the necessity of performing the calculations by hand, with suggestions that using a computer might simplify the process.
  • One participant mentions using the Gram-Schmidt process and expresses intent to present their work in LaTeX.
  • Another participant questions the approach being taken, suggesting that there may be simpler methods available, such as using a recurrence relation.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best method for obtaining the orthogonal polynomials, with multiple viewpoints on the approach and the necessity of using LaTeX for clarity. The discussion remains unresolved regarding the optimal strategy for the calculations.

Contextual Notes

Some limitations are noted, including the complexity of integration and the potential for tedious calculations when done by hand. The discussion also reflects a dependence on the clarity of mathematical presentation and the choice of methods for deriving the polynomials.

Hello everyone,
I need some help with this solution. I'm trying to obtain a set of orthogonal polynomials up to the 7th term. I think i got it up to the 6th term, but the integration is getting more complex. I'm not sure if I'm on the right track. Please help

Could you write the recursion relation, preferably in Latex?

Nobody wants to wade through your hand-written figures. If you want a response, you're going to have to learn how to enter it into latex.

I haven't read your images, but it seems to me like you're describing the Legendre polynomials (https://en.wikipedia.org/wiki/Legen...ition_by_construction_as_an_orthogonal_system). If so, you can check your work there.

Is there a reason you have to do this calculation by hand (instead of using a computer)? I would expect it to be very tedious.
I'm using Gram-Schmidt. I'll type it out using Latex
 
If you mean typing out all your handwriting, first please explain why you seem to be doing it the hard way (rather than using the recurrence relation for example).
