Beliebt Geometry >

(x^2)/(81)+(y^2)/(25)=1

Lösung

\frac{x ^{2}}{81} + \frac{y ^{2}}{25} = 1

Lösung

(h, k) = (0, 0), a = 9, b = 5

Schritte zur Lösung

\frac{x ^{2}}{81} + \frac{y ^{2}}{25} = 1

Rewrite

\frac{x ^{2}}{81} + \frac{y ^{2}}{25} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{9 ^{2}} + \frac{( y - 0 ) ^{2}}{5 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 9, b = 5

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 9, b = 5

(x^2-2x+y^2)/(4-y)<14

\frac{x ^{2} - 2 x + y ^{2}}{4 - y} < 14

10x^2+6y^2-60=0

10 x^{2} + 6 y^{2} - 60 = 0

9 y^{2} + x^{2} = 81

((x^2))/9+(((y-1)^2))/(25)=1

\frac{( x ^{2} )}{9} + \frac{( ( y - 1 ) ^{2} )}{25} = 1

((y-2)^2+(x 1/2)^2)/9 =1

\frac{( y - 2 ) ^{2} + ( x \frac{1}{2} ) ^{2}}{9} = 1
