The 14 pages that link to Secant line, each with the reason it gives.

• Tangent spaceCompared with: As two intersections merge, a secant can approach a tangent direction.

• SlopeRelated: Its slope measures average change across an interval of a curve.

• Tangent lineCompared with: Tangents can be obtained as limiting positions of secants as their points converge.

• Convex functionRelated: The convexity inequality places the graph below every chord joining two graph points.

• Power of a pointBroader topic: Its two intersection points supply the distances whose product defines power.

• Difference quotientRelated: Its slope equals the difference quotient between the two intersection inputs.

• ChordCompared with: Unlike a chord, it extends beyond the two intersection points.

• Mean value theoremRelated: Its slope is the interval’s average rate of change that the theorem matches to a tangent slope.

• Intersecting chords theoremRelated: Each chord lies on a secant line passing through the interior intersection.

• Linear approximationRelated: As the second point approaches the expansion point, its slope approaches the tangent slope.

• Secant methodRelated: The method extrapolates each new approximation from a secant line through its latest two points.

• TransversalCompared with: A transversal intersects lines, while a secant is defined by its intersections with a curve.

• Regula falsiRelated: Its intersection with the x-axis provides the next estimate.

• Intersecting secants theoremBroader topic: Each line in the theorem passes through the circle twice.
