Webb3 aug. 2024 · The most straightforward and simple approximation of the first derivative is defined as: f ′ ( x) ≈ f ( x + h) – f ( x) h h > 0 The approximation error of this equation can be found by performing a Taylor expansion of f ( x + h) about x, which gives: f ( x + h) = f ( x) + h f ′ ( x) + h 2 2 f ′ ′ ( ϵ) Webb8 juni 2013 · Subscribe 7.3K views 9 years ago One of the most basic finite differences is the first order forward difference. This can be used to discretize the governing equations. I derive this...
