① This example demonstrates how to generate a 3D solid of revolution by rotating a plane curve and compute its volume, based on a typical question from the 2017 A Level Paper 2. ② Core mathematical concepts include volume of revolution, definite integrals, curve sketching, linear equations, circle equations, dilation transformations, and step functions. ③ Construction highlights: according to the construction summary, GeoGebra commands such as CurveCartesian (to plot the plane curve), Rotate (to revolve the curve around an axis), and Surface (to create the solid's surface) are used, with objects a, b, c, d likely serving as parameters or coordinates to visualize the 3D shape. ④ Suitable for senior high school students (e.g., A Level, IB, or advanced calculus courses) for reviewing applications of integration, and for teachers to demonstrate the geometric meaning and calculation of the volume of revolution formula.

GeoGebra Commands & Parameters

  1. CurveCartesian(sqrt(t) / (a - t^(2)), t, t, 0, 1) → b
  2. Rotate(b, π / 2, xAxis) → c
  3. Surface(c, (2 * π), zAxis) → d
