To use this formula an individual must be mindful of the units of the angle. Radius and segment height 3. The involute of the circle was first studied by Huygens when he was considering clocks without pendula for use on ships at sea. A more sophisticated treatment of the tangent vector of implicit curves caused by intersection of various kinds of surfaces are found in Chap.6. For a circle of radius , The length of the arc MN of the graph of the hyperbolic cosine can be found with a compass. Central angel and sector area 7. In the form above, this curve has arc length function, curvature . L = /180 * r. The orange segments are the base sides of green isosceles triangles. He used the circle involute in his first pendulum clock in an attempt to force the pendulum to swing in the path of a cycloid . The resemblance to the Pythagorean theorem is not accidental.
