A common phrase to be heard in a class room setting is “When am I ever going to use trig?”
Many do not value or appreciate the importance of trigonometry. However, Trigonometry holds a
special place in the hearts of the blood spatter analyst. The blood spatter analyst work very hard using
the known identities and trigonometric functions to find the angle of impact, that is, at what angle was
the person struck, and at what angle the blood fell. Trigonometry is also used in determining the height
of a person, using the angle of impact.
