Matrix and lineear transformations

Click For Summary
SUMMARY

The discussion focuses on the properties of matrix multiplication, specifically for a 2x2 matrix A defined as A = |val1 val2| |val3 1|. The participants explore the result of the multiplication AA^t, where A^t is the transpose of A. It is established that AA^t results in a symmetric matrix, confirming that this property holds true for any 2x2 matrix. The discussion emphasizes the importance of understanding matrix operations and their implications in linear algebra.

PREREQUISITES

i need some help with this question -

lets say if A =

|val1 val2 |
|val3 1 |

what would AA^t equal?

and

AA^t and A^T.T are symmetrical. is this true for any 2x2 matrix?

thanks in advance

What are val1,val2,val3? If they are arbitrary values, try writing out the matrix multiplication and see if you can notice anything special about the matrix obtained. Same approach for the 2nd question.
