3X^2+4Y^2+12X-8Y+9=0

Lösung

3 X^{2} + 4 Y^{2} + 12 X - 8 Y + 9 = 0

Lösung

(h, k) = (- 2, 1), a = \frac{7}{3}, b = \frac{7}{2}

Schritte zur Lösung

3 X^{2} + 4 Y^{2} + 12 X - 8 Y + 9 = 0

Rewrite

3 X^{2} + 4 Y^{2} + 12 X - 8 Y + 9 = 0

in the form of the standard ellipse equation

\frac{( X - ( - 2 ) ) ^{2}}{( \frac{7}{3} ) ^{2}} + \frac{( Y - 1 ) ^{2}}{( \frac{7}{2} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, 1), a = \frac{7}{3}, b = \frac{7}{2}

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 2, 1), a = \frac{7}{3}, b = \frac{7}{2}
