9x^2+25y^2-36x+50y-200=0

Lösung

9 x^{2} + 25 y^{2} - 36 x + 50 y - 200 = 0

(h, k) = (2, - 1), a = 29, b = \frac{3 29}{5}

Schritte zur Lösung

9 x^{2} + 25 y^{2} - 36 x + 50 y - 200 = 0

Rewrite

9 x^{2} + 25 y^{2} - 36 x + 50 y - 200 = 0

in the form of the standard ellipse equation

\frac{( x - 2 ) ^{2}}{( 29 ) ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{( \frac{3 29}{5} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (2, - 1), a = 29, b = \frac{3 29}{5}

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (2, - 1), a = 29, b = \frac{3 29}{5}

\frac{( X + 2 ) ^{2}}{4} + \frac{( y - 3 ) ^{2}}{9} = 1

7 x^{2} + 16 y^{2} - 112 = 0

(x - h)^{2} + (y - k)^{2} = 1

9 x^{2} + 64 y^{2} = 1

y + 2 = \frac{6 - ( \frac{6 y + 2 x}{2 + y} )}{2} x
