With the secant line being the line joining these two points 01 and x cosx you simply write a slope equation change in YChange in X. The slope formula for secant line is same as slope of any line. 1a find the slope of the secant line between x 3 and x 4 Our Lines Equation x-2 f x--- x-5 Secant Line Slope Formula f x₀-f x₁ m-------- x₀-x₁Tuesday September 25 12 5.
This calculus video tutorial explains how to find the equation of a secant line that intersects the curve at two pointsMy Website.
Slope of the Secant Line. The secant method can be thought of as a finite difference approximation of Newtons method where a derivative is replaced by a secant line. In this video we use the slopes of secant lines to calculate the slope of the tangent line. To determine the slope of a line at a given point one must first find two points of the secant line and then find the slope of the line between the two points.
