Η Εξίσωση Της Αγάπης


Input:

    x^2+(y-x^2^(1\/3))^2 = 1


    Implicit plot:



    Alternate forms:

    (x^2^(1\/3)-y)^2+x^2 = 1

    -2 x^2^(1\/3) y+x^2+(x^2)^(2\/3)+y^2 = 1

    x^2+(y-x^(2\/3) e^((2 i pi (left floor)1\/2-(arg(x))\/pi(right floor))\/3))^2 = 1

    RawBoxes[RowBox[{arg, RowBox[{(, z, )}]}]] is the complex argument »
    RawBoxes[TemplateBox[{x}, Floor]] is the floor function »


    Alternate form assuming x and y are positive:

    (x^(2\/3)-y)^2+x^2 = 1


    Integer solutions:

    x = ±1,   y = 1

    x = 0,   y = ±1


    Solutions for the variable y:

    y = x^2^(1\/3)-sqrt(1-x^2)

    y = sqrt(1-x^2)+x^2^(1\/3)
