To determine the arc length that will maximize the volume of the cone,
press
calculator will identify the maximum of the graph selected.
Equation:
To determine the arc length that must be removed to maximize the volume of
the cone symbolically requires knowledge of the concept of derivative. This is
beyond our expectations of students studying advanced algebraic concepts.
Yet, notably, graphing technology often provides students with access to
mathematical concepts that they may not be prepared to investigate
symbolically.
