Problem 35
Question
What is a secant line?
Step-by-Step Solution
Verified Answer
A secant line is a line that intersects a curve at two or more points, used often in geometry and calculus to approximate the behavior of a curve.
1Step 1: Definition
A secant line is a line that intersects a curve at two or more points. In geometry, it is often used to approximate the behavior of a curve around a certain point.
2Step 2: Illustrative Example
For example, consider a circle. A line passing through any two points on the circle is a secant line. It is different from a tangent line, which touches the circle at only a single point.
3Step 3: Further Explanation
Moreover, in calculus, a secant line is usually referred when speaking of the average rate of change of a function between two points.
