Math 110 Homework 3 Solutions

By the Chinese Remainder Theorem, we already knew that the map (Z=mnZ) ! (Z=mZ) (Z=nZ) c(mod nm) 7! c(mod m) ;c(mod n) is one-to-one and onto. Now we know that it maps every unit c(mod mn) to a pair of units c(mod m) ;c(mod n) , and conversely that every pair of units is in the image of a unit c(mod mn). We conclude that the map re-

The formula for the orthogonal projection

Let V be a subspace of Rn. To nd the matrix of the orthogonal projection onto V, the way we rst discussed, takes three steps: (1) Find a basis ~v 1, ~v 2, ..., ~v m for V. (2) Turn the basis ~v i into an orthonormal basis ~u i, using the Gram-Schmidt algorithm. (3) Your answer is P = P ~u i~uT i. Note that this is an n n matrix, we are ...
