Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 5x2 region with the numbers 1-10 once. The difference is how you arrive at those numbers. The objective is to fill the grid with numbers from 1 to 10 in a way that the following conditions are met: Each row, column, and nonet contains each number exactly once.The sum of all numbers in a cage must match the small number printed in its corner.No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 10 cells.

Geared toward undergraduate students, this text illustrates the use of vectors as a mathematical tool in plane synthetic geometry, plane and spherical trigonometry, and analytic geometry of two- and three-dimensional space. Its rigorous development includes a complete treatment of the algebra of vectors in the first two chapters. Among the text's outstanding features are numbered definitions and theorems in the development of vector algebra, which appear in italics for easy reference. Most of the theorems include proofs, and coordinate position vectors receive an in-depth treatment. Key concepts for generalized vector spaces are clearly presented and developed, and 57 worked-out illustrative examples aid students in mastering the concepts. A total of 258 exercise problems offer supplements to theories or provide the opportunity to reinforce the understanding of applications, and answers to odd-numbered exercises appear at the end of the book.
