9x^2+16y^2-90x-160y+481=0

Lösung

9 x^{2} + 16 y^{2} - 90 x - 160 y + 481 = 0

Lösung

(h, k) = (5, 5), a = 4, b = 3

Schritte zur Lösung

9 x^{2} + 16 y^{2} - 90 x - 160 y + 481 = 0

Rewrite

9 x^{2} + 16 y^{2} - 90 x - 160 y + 481 = 0

in the form of the standard ellipse equation

\frac{( x - 5 ) ^{2}}{4 ^{2}} + \frac{( y - 5 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (5, 5), a = 4, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (5, 5), a = 4, b = 3
