§2 Bisection method 试位法/ Regula Falsi Method Is it really better than Bisection method? (b,∫(b) (a+b)/2 f∫(a) (a,(a) X=a f∫(b)-∫(a) 注:试位法每次迭代比二分法多算一次乘法,而且不保证 收敛。➢ 试位法 /* Regula Falsi Method */ a b (a+b)/2 x* (a, f (a)) (b, f (b)) (b a) f b f a f a x a  − − = − ( ) ( ) ( ) Is it really better than Bisection Method? 注：试位法每次迭代比二分法多算一次乘法，而且不保证 收敛。 §2 Bisection Method
