Fixed points of sin x

WebFeb 28, 2024 · The fixed point (s) are where f ( x) = x. They are attractive when f ′ ( x) < 1 (equal to 1 is more complex but not relevant here) But why is the fixed point near ln 2? ln 2 is the solution of e x − 2 = 0. Instead of the roots of f ( x) − x, consider the roots of g ( x) = − cos ( x) + arcsin ( x). WebHowever, g (x) has fixed points at x = 0 and x = 1/2. Example: Consider the equation x = 1 + 0.4 sin x, with g ( x) = 1 + 0.4 sin x. Note that g (x) is a continuous functions everywhere and 0.6 ≤ g ( x) ≤ 1.4 for any x ∈ R. Its derivative g ′ ( x) = 0.4 cos x ≤ 0.4 < 1.
