The predator equation becomes d y d t = δ x y − γ y . {\displaystyle {\frac {dy}{dt}}=\delta xy-\gamma y.} In this equation, δxy represents the growth of the predator population.
Predatorekvationen blir: d y d t = δ x y − γ y {\displaystyle {\frac {dy}{dt}}=\delta xy-\gamma y} I denna ekvation så representerar δxy tillväxten av predatorpopulationen.
