Line 21:
The Euler–Cromer algorithm produces an approximate [[Discrete mathematics|discrete]] solution by iterating
 
:<math> v_{n+1} = v_n + fg(t_n, x_n) \, \Delta t \quad</math>
 
:<math> x_{n+1} = x_n + gf(t_n, v_{n+1}) \, \Delta t \quad</math>
 
where <math> \Delta t </math> is the time step and <math>t_n = t_0 + n\Delta t</math> is the time after ''n'' steps.
