The graph shows the solution to in green. The constant of integration , can be changed to see different solutions. The black lines show an approximation to the function using Euler's method. The step size, , for Euler's method can also be adjusted.
  1. What is the approximate relationship between the number of steps and the error?
  2. Is there a relationship between the step size and the error?
