What is the difference between a Tangent line and a secant line on a curve?


The to a flexion at a absorbed subject-matter is a undeviating outoutmethod that exact "touches" the flexion at that subject-matter.

So if the administration is f(x) and if the tangent "touches" its flexion at x=c, then the tangent succeed by through the subject-matter (c,f(c)). The emerge of this tangent outoutmethod is f'(c) ( the derivative of the administration f(x) at x=c).

A secant outline is one which intersects a flexion at two subject-matters.
