The length of a polar curve can be calculated with an arc length integral. For a polar curve r = f (θ) r = f(\theta ) r = f (θ), given that the polar curve's first derivative is everywhere continuous, and the domain does not cause the polar curve to retrace itself, the arc length on α ⩽ θ ⩽ β \alpha \leqslant \theta \leqslant \beta α. Recall that if is a vector-valued function where . is continuous. The curve defined by is traversed once for .; The arc length of the curve from is given by This is all good and well; however, the integral could be quite difficult to compute. In this section, we see a new description of the curve drawn by , we'll call it where the same curve is drawn by both and and we have that This is.

Imagine we want to find the length of a curve between two points. And the curve is smooth (the derivative is continuous). First we break the curve into small lengths and use the Distance Between 2 Points formula on each length to come up with an approximate answer: The distance from x 0 to x 1 is: S 1 = √ (x 1 − x 0) 2 + (y 1 − y 0) 2.

For your first example: rx = ry =25 and x-axis-rotation =0, since you want a circle and not an ellipse. You can compute both the starting coordinates (which you should M ove to) and ending coordinates (x, y) using the function above, yielding (200, 175) and about (182.322, 217.678), respectively. And, since you know that diameter JL equals 24cm, that the radius (half the length of the diameter) equals 12 cm. So θ = 120 and r = 12 θ = 120 and r = 12 Now that you know the value of θ and r, you can substitute those values into the Arc Length Formula and solve as follows: Replace θ with 120. Replace r with 12. Simplify the numerator.
