This example demonstrates finding the tangent slope (instantaneous rate of change) at x=1 using successive approximations with secant lines. Key mathematical concepts include limits and derivatives. GeoGebra commands used include Point, Line, and Tangent. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Point(xAxis) → B
  2. If(soccer, fs(x1), fc(x1)) → y1
  3. Line(P1, P2) → secant
  4. Segment(B, P2) → seg
  5. Segment(P2, (0, y2)) → seg2
  6. Tangent((1, 4), fc) → tanline

AI Drawing Prompt Reference

Draw a function graph and approximate the tangent line at x=1 with two line segments. First, draw a point B on the x-axis, then draw a secant line through B and another point on the function graph. Next, draw a line segment from the other end of the secant to the y-axis. Finally, draw the tangent line at x=1 on the function.
