Regular Expressions: The Power of Perl

Regular Expressions: The Power of Perl 1.What is a regular expression (regex) ? - it is a ‘description’ for a group of characters you want to search for in a string, a file, a website, etc... - think of the group of characters as a ‘pattern’ that you want to find within a string.

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 ...

Quantifiers and Negation - University of Washington

negation of the quantifiers is a quick exercise that doesn’t require the use of any sophisticated logic rules, you just ‘flip’ the quantifiers, then negate the statement (when you get to the statement then you will need logic rules to negate).
