Lab14 This is so Matrice-sy!
1) Area of Stanley
The town of Stanley appears in the following GeoGebra Applet as an image from Google Maps. To estimate the area of Stanley on our scaled map,
*The scale factor is 1 grid unit = 600 ft or 1 grid unit=0.0129 miles
a.) Plot the three points (14,10) , (11,4) and (3,8).
b.) Use the method described in section 8.5 to find the area of the triangle created by the three vertices (using the determinant of the three by three matrix).
c.) Use the polygon tool 
to draw the triangle created by points C, D and E.
d.) Type in area[C,D,E] or area[poly1] to have GeoGebra calculate the area of the region.
to draw the triangle created by points C, D and E.
d.) Type in area[C,D,E] or area[poly1] to have GeoGebra calculate the area of the region.2.) Alan Turing
Codes are used in many areas of life some personal and some cooperative This section focuses on the use of decoding matrices. Research the peculiar life of Alan Turing.
3) Cryptology and Cyber Security
According to Wikipedia, Cryptography or cryptology; is the practice and study of techniques for secure communication in the presence of third parties called adversaries. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message (Alice) shared the decoding technique needed to recover the original information only with intended recipients (Bob), thereby precluding unwanted persons (Eve) from doing the same. Since World War I and the advent of the computer, the methods used to carry out cryptology have become increasingly complex and its application more widespread.
