Example #5. An Archimedes' spiral is the trajectory of a point moving uniformly on a straight line of a plane while the lineturns itself uniformly around one of its points. An example is the rotation of the stylus on a good old vinyl disk. The curveof one type of an Archimedes' spiral is given by the mathematical function , where is the radius from theorigin and is the angle the line makes with the axis. Let us calculate the following parameters for one turn(that is changes from 0 to 2 ):
The circumference of the curve1.The area enclosed within the curve2.
