| Hello. After the last class on game theory, all the participants have received an email for the recording. That email said "We will share a link to the Introduction to Game Theory framework, including access to the quizzes and final exam, in an... |
| Thanks! I'll just point out that Gianluca's method is basically the standard way you'd do this. The only reason to use linear combinations of eigenvectors is to turn matrix multiplication into scalar multiplication (which could give performance... |
| Hello Václav, I wanted to clarify that, in order to earn Completion certification via the Daily Study Group, you need to have passed all of the quizzes. It looks like you passed the exam (Feb 6) but did not take the quizzes. Can you please... |
| Sure, you can think of `Eigenvalues` as a pure function, but that's beside the point in terms of an explanation. `Eigenvalues` returns a list, and `Part` (I'm using the `[[]]` syntax for `Part`) extracts elements from a list. So, when you said you... |
| You've misplaced the brackets. In the first plot you used {{6/10, 1/2}, {- 7, 6/5}} . {x, y} but in the later ones you used {{6/10, 1/2}, {-pred, 6/5} . {x, y}} |
| Thanks Again, your answer is exactly what I needed. |
| Along the unit circle, the eigenvectors with real eigenvalue are the arrows that are orthogonal to the circle. They should be easy to spot visually. The length of the vector indicates the eigenvalue. Merry Christmas! |

| Hi; To access a specific cell (specific row & column) in a Matrix you can use the `Part[]` function - for example `A[[1,1]]` gives the value of the cell in row 1, column 1 of Matrix A. Can the Matrix cell can be accessed by using a subscript and... |
