WebNov 10, 2024 · In the two-dimensional coordinate system, parametric equations are useful for describing curves that are not necessarily functions. The parameter is an independent variable that both x and y depend on, and as the parameter increases, the values of x and y trace out a path along a plane curve. WebA superellipse is a curve with Cartesian equation x/a ^r+ y/b ^r=1, (1) first discussed in 1818 by Lamé. A superellipse may be described parametrically by x = acos^(2/r)t (2) y = bsin^(2/r)t. (3) The restriction to r>2 is sometimes made. The generalization to a three-dimensional surface is known as a superellipsoid. Superellipses with a=b are also known …
