25x^{(2)}+4y^{(2)}=84

Lösung

25 x^{(2)} + 4 y^{(2)} = 84

Lösung

(h, k) = (0, 0), a = \frac{2 21}{5}, b = 21

Schritte zur Lösung

25 x^{2} + 4 y^{2} = 84

Rewrite

25 x^{2} + 4 y^{2} = 84

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{( \frac{2 21}{5} ) ^{2}} + \frac{( y - 0 ) ^{2}}{( 21 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = \frac{2 21}{5}, b = 21

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 21, a = \frac{2 21}{5}
