① This interactive practice tool demonstrates how to find the interval of convergence for Taylor series and provides immediate feedback on answers. ② Core mathematical concepts include Taylor series, power series, radius and interval of convergence, and convergence tests such as the ratio test or root test. ③ Construction highlights: The applet uses GeoGebra commands like Random, RandomDiscrete, and RandomElement to generate random series terms, Simplify and FractionText to manage expressions, Textfield and InputBox for user input, and If statements to check correctness. Buttons (button1-4) control the practice flow, while text objects (leftend, rightend, ioc) display the endpoints and interval. ④ Suitable for university calculus or advanced high school students learning power series convergence, ideal for self-paced practice and reinforcement.

AI Drawing Prompt Reference

Create an interactive math practice graphic for Taylor series convergence intervals. The center shows a randomly generated power series expression with fractional coefficients and exponents. Below are three input fields for left endpoint, right endpoint, and interval of convergence. Four buttons control the practice flow. The graphic displays the interval endpoints and indicates the correct interval type based on conditions. The layout is clean, suitable for self-paced student practice with immediate feedback.
