B.1 Snippets for Scripts

Area = 25 m²  
Volume = 3.2 m³  
Density of water = 1000 kg/m³  
Angle = 45°  
Angular speed = 12 s⁻¹  

Area = π·r²  

Law of sines:
T₁ / sin(θ₁) = T₂ / sin(θ₂) = W / sin(θ₃)

Law of cosines:
cos(θ) = (a² + b² − c²) / (2ab)
cos(θₚ) = (J² + T² − P²) / (2·J·T)

Energy equation:
P₁ + ½ρv₁² + ρgz₁ = P₂ + ½ρv₂² + ρgz₂
