Click For Summary
The discussion focuses on finding the basis and dimension for the eigenspaces of the matrix with eigenvalues λ = 1 and λ = 6. The user correctly identifies the eigenspace for λ = 1 as span(-2/3, 1) and for λ = 6 as span(1, 1), both having a dimension of 1. Clarification is sought on the correctness of these bases and the notation used. Other participants confirm that the user's findings are accurate. The conversation concludes with the user expressing satisfaction in resolving their query.

Homework Statement


Find a basis and dimension for each eigenspace of the matrix:

4 2
3 3

Homework Equations


The Attempt at a Solution


I found the eigenvalues lambda = 1, 6. When trying to find the eigenspace for lambda = 1, I try to solve for x and y here:

|-3 -2| |x| = |0|
|-3 -2| |y| = |0|

I'm not sure how to do the matrix notation on here but I hope it is clear enough. Since I get the same equation twice in the system of equations, is this the right basis: span(-2/3, 1)?

edit: can someone also see if I did the basis for the 2nd eigenvalue (lambda = 6) correctly? I get the basis to be span(1, 1).
So each has dimension of 1

Um, yes. If I'm reading your notation correctly, you have the right eigenspace for both. Is this a question, or just a homework check?
 
It was originally going to be a question but I kind of figured it out as I was typing it :)
So I was just making sure.
Thanks
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
