Final answer:
The arc length function, denoted by A(t), represents the distance traveled along a circular path when t > 0. It is related to the radius of curvature, r.
Step-by-step explanation:
The arc length function, denoted by A(t), represents the distance traveled along a circular path when t > 0. It is related to the radius of curvature, r. The arc length, As, is calculated using the formula:
As = r * A
The path traced by r when t > 0 depends on the specific problem or context.
