By raising a trigonometric function to an exponent, the degree of curvature will increase, emphasizing the outermost boundaries of that particular shape. The higher the power, the steeper the apex of the shape will be. If a shape is raised to an even power, its orientation will be mirrored. For example, if all odd powers point upwards, all even powers will point downward. Although pinching will give the illusion of an edge, the edge will have a slight rounding to maintain the property of continuity.
