Vector Countdown

7460 /www/nrich/html/content/id/7460/ 2 2011-06-14T11:38:33 <mdoxml version="1.0"> Vectors in three dimensions can be added, subtracted and 'multiplied' using the scalar and cross products. They can also be multiplied or divided by a scalar. You can also find the modulus of a vector. Why not put your knowledge and intuition concerning vectors to the test in a game of vector countdown? You can use each vector given at most once, but you can use the results of a vector calculation in a new game; if you need a scalar then you will need to use the modulus or scalar product operations on one or two of the vectors. We recommend about 5 minutes per game. You can determine how close you get to the target by looking at the modulus of the difference between your answer and the target vector. <mdo:flash height="300" width="550"><param name="allowfullscreen" value="true" ></param><param value="true" name="allowfullscreen" ></param><param value="/content/id/7460/countdown.swf" name="movie" ></param><param value="8" name="flashplayerversion" ></param></mdo:flash> Extension: If you wish to develop your IT skills, why not try implementing a version of this game on a spreadsheet or in code? As an extra challenge you might try to implement a version in which you know that there is always an exact solution for every game played. </mdoxml> 2 5 0 0 0 0 1 Vector Countdown Play countdown with vectors.
