25x^2+16y^2=400

Lösung

25 x^{2} + 16 y^{2} = 400

Lösung

(h, k) = (0, 0), a = 4, b = 5

Schritte zur Lösung

25 x^{2} + 16 y^{2} = 400

Rewrite

25 x^{2} + 16 y^{2} = 400

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{4 ^{2}} + \frac{( y - 0 ) ^{2}}{5 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 4, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 5, a = 4
