Secant Line Calculator: A Comprehensive Guide to Calculating Tangents and Slopes

The secant line, also known as the chord of a circle, is a straight line connecting two points on a circle's circumference. The length of the secant line is equal to the chord length of the circle. The secant line calculator is a mathematical tool used to calculate the length of a secant line and the angle between the secant line and the tangent line at the point where the secant line intersects the circle.

How to Use a Secant Line Calculator

To use a secant line calculator, you will need to know the following information:

• The coordinates of the two points on the circle's circumference that the secant line connects.
• The radius of the circle.

Once you have this information, you can enter it into the secant line calculator. The calculator will then calculate the length of the secant line and the angle between the secant line and the tangent line.

Applications of Secant Line Calculators

Secant line calculators have a wide range of applications in various fields, including:

• Geometry: Calculating the length of chords and secant lines in circles.
• Trigonometry: Calculating the sine, cosine, and tangent of angles in right triangles.
• Calculus: Calculating the slope of a curve at a given point.
• Physics: Calculating the velocity and acceleration of an object moving in a circular path.
