Question 30457: Circle Squared Remainder at a Fixed Horizontal Offset

Original question and givens

Use a circle boundary, not a disk, in one equal-unit orthogonal Euclidean L2 frame with nonnegative integer radius. For r=0 only the center is on the circle. r=7, horizontal displacement dx=-1, ordered candidate y values=[0, 7, 8] for points (dx,y). Give (required=r²−dx², three y²−required residuals, three boundary-eligibility values).

Step-by-step derivation

source roles = [qf-density14-circle-horizontal-section-candidates, density14_circle_horizontal_section_candidates, finite_integer_circle_boundary_protocol]

derived = [[required_vertical_square, ALL_squared_residuals, ALL_boundary_flags]]

Circle ORIGINAL nonnegative radius squared := mul(7, 7)

Circle ORIGINAL nonnegative radius squared = 49

source roles = [7, orthogonal_equal_unit]

derived = [49]

Circle ORIGINAL horizontal displacement squared := mul(-1, -1)

Circle ORIGINAL horizontal displacement squared = 1

Circle ORIGINAL required vertical square := sub(49, 1)

Circle ORIGINAL required vertical square = 48

Circle ORIGINAL vertical candidate0 squared := mul(0, 0)

Circle ORIGINAL vertical candidate0 squared = 0

Circle ORIGINAL candidate0 square minus required := sub(0, 48)

Circle ORIGINAL candidate0 square minus required = -48

Circle ORIGINAL vertical candidate1 squared := mul(7, 7)

Circle ORIGINAL vertical candidate1 squared = 49

Circle ORIGINAL candidate1 square minus required := sub(49, 48)

Circle ORIGINAL candidate1 square minus required = 1

Circle ORIGINAL vertical candidate2 squared := mul(8, 8)

Circle ORIGINAL vertical candidate2 squared = 64

Circle ORIGINAL candidate2 square minus required := sub(64, 48)

Circle ORIGINAL candidate2 square minus required = 16

source roles = [7, -1, [0, 7, 8]]

derived = [48, [-48, 1, 16], [No, No, No]]
