This art history video discussion looks at Claus Sluter's (with Claus de Werve) "The Well of Moses", 1395-1405 (calvary finished 1399, prophets 1402-05, painted by Jean Malouel c. 1402), Asnières stone with gilding and polychromy, slightly less than 7 meters high, originally close to 13 meters with cross. Located on the grounds of the former Chartreuse de Champmol, a Carthusian monastery in Dijon, France established by Philip the Bold, Duke of Burgundy. The prophets depicted include: Moses, David, Jeremiah, Zachariah, Daniel, and Isaiah.
Sal solves a linear system with 3 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Gaussian Elimination is the method, reduced row echelon is just the final result.
Determining whether 3 vectors are linearly independent and/or span R3. Created by Sal Khan.
