WebBisection Method. The Intermediate Value Theorem says that if f ( x) is a continuous function between a and b, and sign ( f ( a)) ≠ sign ( f ( b)), then there must be a c, such that a < c < b and f ( c) = 0. This is illustrated in the following figure. The bisection method uses the intermediate value theorem iteratively to find roots. WebMar 17, 2024 · The `bisect` module in Python provides two functions, `bisect_left` and `bisect_right`, which can be used to efficiently find an insertion point for a value into a sorted list.
