This page is not complete.
Contribute with things that are necessary to know by heart.
- Stability, solution goes -> 0?
- Residual for step methods: Taylor expand the formula and see what order the RHS is.
- Stability region,$y' = f(y,t)$
- \(Re( h\cdot f(y) ) < 0\) for trapetzoid
- |1+ hf| < 1 for Explicit euler
- |1+ hf| > 1 for implicit euler
