Project Name : Bloody Trigonometry
Theme Name : Mathematics in Everyday Life
This project is about the mathematical calculations involved in forensic science. We took up this project as there are no blood spatter analysts in India. Our topic focuses on blood spatter analysis. Through blood spatter analysis, we can determine:
a) The angle of impact 0 = sin–1 (width/ length).
b) The area of convergence (Position of the victim).
c) The area of origin (Height of original of blood source).
The three methods to determine the area of origin are:
I) Tangent method (h = tan I X d)
II) Graphical method
III) Triangulation or string method
Estimation of stature from long bones
I – Type of weapon used
II – Type of velocity – from droplet size (high, medium, low)
Sequence of event occurred
Thus, we have established the fact that mathematics has become a universal language and has become a part of everyday life.
