Hello, I need help with writing code euler's method. Solved the task set out in annex explicit function but my teacher was not satisfied. He wanted me wrote Euler method alone. Does anyone of you have an idea how to do it?
NDSolve[{y''[t] - (1 - y[t]*y[t])*y'[t] + y[t] == 0, y[0] == 1, y'[0] == 1}, y, {t, 0, 10},
Method -> "ExplicitEuler", "StartingStepSize" -> 0.25]
