(3x-3)^2+(-2y-4)^2=43+9+16

Lösung

(3 x - 3)^{2} + (- 2 y - 4)^{2} = 43 + 9 + 16

(h, k) = (1, - 2), a = \frac{2 17}{3}, b = 17

Schritte zur Lösung

(3 x - 3)^{2} + (- 2 y - 4)^{2} = 43 + 9 + 16

Rewrite

(3 x - 3)^{2} + (- 2 y - 4)^{2} = 43 + 9 + 16

in the form of the standard ellipse equation

\frac{( x - 1 ) ^{2}}{( \frac{2 17}{3} ) ^{2}} + \frac{( y - ( - 2 ) ) ^{2}}{( 17 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (1, - 2), a = \frac{2 17}{3}, b = 17

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, - 2), b = 17, a = \frac{2 17}{3}

36 x^{2} + 81 y^{2} = 49

49 x^{2} + 16 y^{2} - 784 = 0

9 x^{2} + 4 y^{2} - 54 x - 16 y + 61 = 0

\frac{y ^{2}}{16} + \frac{z ^{2}}{9} = 1

(x - 4)^{2} + 2 (y - 3)^{2} = 1
