Function and Derivative by David Douis
Loading the math board and drawing, please wait…
This example demonstrates the dynamic relationship between a function and its derivative. Core math concepts include function, derivative, slope, and dynamic visualization. Construction highlights: uses Textfield for text, Derivative command for slope calculation, involving objects f, a, InputBox1, A, f', m, InputBox2. Suitable for high school mathematics teaching or self-learning to understand the geometric meaning of the rate of change and derivatives.

AI Drawing Prompt Reference
Draw a coordinate plane with a user‑defined function curve, include two text input boxes for entering the function expression and an x‑value, automatically plot the derivative curve, and show the tangent line at the chosen x‑value with its slope, illustrating the dynamic relationship between a function and its derivative. The figure should update in real time as the user changes the function or the x‑value, displaying both the original curve and its derivative on the same axes, with a clear indication of the point of tangency and the numeric slope value.
