• The Lotka-Volterra equations are a system of two first-order, nonlinear ODEs that describe the populations of predators and prey in a biological system. Over time, the populations of the predators and prey change according to the equations :

^dx/_dt = α x - β xy
^dy/_dt = δ xy - γ y

• Population over time, Phase plot
• Comparison of the solutions for all of the initial conditions
