Remember 1C or Physics 4A Ballistics?
We know the role of calculus in this realm
Lets work backwards!
Who shot at me?

i and j are the rows and columns of a map, respectivelyn is the number of the crime (1= first crime, 2 = second
crime...)c is the total number of crimesB represents the size of the buffer zonek is a constantPhi, f, and g is determined by checking against past crime data
The math behind the magic

The probability of crime locations decreases as the distance from the hot zone increases (inversely proportional), shown by first fraction
Second fraction is the difference between the buffer zone and the locations of the crimes
