About this document
Estimating Tangent Slopes with Secants by Lord Abraham Al-Rajhi is a document available to read on EtoBox.
The document discusses approximating the slope of a tangent line using secant lines. It uses an online tool to investigate how the slope of a secant line (Δy/Δx) approaches the slope of the tangent line as Δx approaches 0, for three examples: 1) The function f(x) = 0.5x^3 - x at x = -0.75, finding that Δx needs to be ≤ 0.25. 2) The same function at x = 0, finding that Δx needs to be ≤ 0.25. 3) The same function at x = 0.75, finding that Δx needs to be ≤ 0.25.
