Gerschgorins theorem in eigenvalue problem

Click For Summary
SUMMARY

The discussion centers on applying Gerschgorin's theorem to analyze the eigenvalue problem defined by the differential equation y'' + λy = 0 with boundary conditions y(0) = y(1) = 0. Participants emphasize the importance of understanding the implications of matrix size on eigenvalues and the necessity of solving the eigenvalue problem accurately. The conversation highlights the need for foundational knowledge in differential equations and matrix theory to effectively utilize Gerschgorin's theorem in this context.

Hi. I was wondering if anyone can give me advice on how to answer the following question.

Use Gerschgorin's theorem to show the effect of increasing the size of the matrix in your solution to the eigenvalue problem: y''+lambda*y=0 y(0)=y(1)=0

Thanks

Main issue is that I don't really know how to solve the eigenvalue problem.
