4. Aprēķini
Jāaprēķina elipses līnijas pirmos 7 punktus, elipses rādiusus jāpaņem pēc sava varianta (R1=5, R2=8).
Risinājums:
1) I etaps, Sākuma punkts (xo; yo)=(0;ry)=(0;8)
2) p10= 8^2-5^2*8+0.25*5^2= - 129.75<0
3) ry2x0
4) K=1; (2;7), p1=190.25+2*(8^2)*(2+1)+(8^2)-2*(5^2)*(7-1)=338.25>0
5) K=2; (3; 6), p1=338.25+2*(8^2)*(3+1)+(8^2)-2*(5^2)*(6-1)=664.25>0
6) ry2x
7) K=0; (1; 7), p2=-368.75+2*(8^2)*(1+1)+(5^2)-2*(5^2)*(7-1)=-387.75<0
8) K=1; (2; 6), p2=-387.75+2*(8^2)*(2+1)+(5^2)-2*(5^2)(6-1)=-228.75<0
9) K=2; (3; 5), p2=-228.75+2*(8^2)*(3+1)+(5^2)-2*(5^2)*(5-1)=108.25>0
10) K=3; (3; 4), p2=108.25-2*(5^2)*(4-1)+(5^2)=-16.75<0
Atbilde: (0;8), (1; 8), (2; 7), (3; 6), (1; 7), (2; 6), (3; 5), (3; 4).
