To find the length of an arc covering π/3 radians on the circle, you can use the formula for the length of an arc:

Arc Length = r * θ

Where: r is the radius of the circle, θ is the angle in radians subtended by the arc.

First, find the radius of the circle using the distance formula between the center and any point on the circle:

r = √[(x2 - x1)^2 + (y2 - y1)^2]

Substitute the given coordinates: r = √[(2 - 4)^2 + (4 - 1)^2] r = √[(-2)^2 + (3)^2] r = √[4 + 9] r = √13

Now, plug in the values of r and θ into the formula for arc length:

Arc Length = (√13) * (π/3)

Arc Length ≈ (π/3) * √13

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
