Symbols: a : major radius on x axis A : area in 1st quadrant b : minor radius on y axis Ax : partial area n : power varies from 1 to ∞ Pw : wetted perimeter P : perimeter in 4 quadrants Rh : hydraulic radius L : arc length in 1st quadrant Lx : partial arc length At : total area in 4 quadrants Section 1: Introduction This study started from replying a question "What's the perimeter of Ellipse?",in1988,the answer I've found in a simple form wrote in my non printed book "The Elliptical Shape" in 1992 ,which registered in the National Library ,Press Department-Jordan under the serial no.446/8/1992,then followed the research in 1996 to obtain the approximations of the complete area and arc length, perimeter for the 𝒙𝒏 𝒚𝒏 general function 𝒂𝒏 + 𝒃𝒏 = 𝟏, then for partial area in2004. Several helpful tools used in the research, such as theoretical scientific base from what studied in mathematics in general and especially in calculus, statics, engineering mathematics, with other special subjects such as special functions, drawing ,also the collected knowledge from reference books, researches and web sites with the aid of programmable calculator and computer programs. It's an applicable research for different sectors such as applied mathematics, statistics , physics, hydraulics, heat transfer, aerodynamic , mechatronics, antennas, botany, live beings, medical images, computer vision, machineries, technicians, designer engineers, etc.. .Equations can be used to approximate the complete and incomplete elliptic integrals of second kind, gamma and beta functions also hypergeometric functions. Superquadrics as 3D bodies and special cases of Superformula in 2D & 3D plans can be studied. Results of equations gives good approximations as indicated in the tables. References listed at the end which make an obvious image about the subject .
