👉 In mathematics, a secant is a line segment that joins two points on a curve. It represents the ratio of the change in the y-coordinate to the change in the x-coordinate for an infinitesimal change in x over the corresponding infinitesimal change in y.
For example, if we have a function f(x) = 3x^2 - 4x + 1 and we want to find the secant between two points (a,b), then:
- The first point on the
secant
