This is the math-heavy section. Given a stain that is elliptical, you measure:
In the world of forensic science, few pieces of evidence are as visually striking—or as scientifically revealing—as bloodstain pattern analysis (BPA). For students navigating the complexities of forensic coursework, specifically documents often labeled with codes like "FSB09," the "Blood Spatter Worksheet" is a rite of passage. It represents the transition from theoretical knowledge to practical application.
Use this article as your study guide. Master the difference between arcsin and tangent. Understand why a satellite spatter forms. If you can explain why the answer is 30 degrees, you have truly learned forensic science. This is the math-heavy section
By analyzing blood spatter, students learn to:
Ratio = 1.0 / 2.0 = 0.5 → sin⁻¹(0.5) = 30° b) Height = 50 cm × tan(30°) ≈ 50 × 0.577 = 28.9 cm It represents the transition from theoretical knowledge to
The FSB09 worksheet usually includes a chart where you classify stains by velocity.
Angle of Impact = arcsin (Width / Length) Understand why a satellite spatter forms
You will be asked to match terms to definitions. Here are the likely answers:
