What this demonstration shows
This 27-second product demonstration shows a question becoming a worked explanation. The example differentiates x² sin x using the product rule. It demonstrates the interface; it is not a study of learning outcomes.
Visual description
The question
The learner asks about differentiating a product of two functions.
The method
The response separates the two factors and applies the product rule.
The result
The worked derivative is 2x sin x + x² cos x. Checking the intermediate steps matters as much as reading the final line.
