The first man knows as a Vertex curve found by quadratic equations.
The Second is to do with the intersection between 2 shapes one from the outer surface wave of a waved circle the other the inner waved circle at the point of 2 intersections along proportioned chimeric R-axial (between triangle circle and square circle) axis as a description of connected waved bulbs as to measure perfectly and optimally a natural curved world.
The Third an infinitely exponential curved rhombus forged at the axis where (between square and triangle)circle exponential infinitely proportions with the distribution of transcendental primality across (between square and triangle Pi&Pi/2) Binary.
