(x^2)/(15)+(y^2)/(16)=1

\frac{x ^{2}}{15} + \frac{y ^{2}}{16} = 1

(h, k) = (0, 0), a = 15, b = 4

Solution steps

\frac{x ^{2}}{15} + \frac{y ^{2}}{16} = 1

Rewrite

\frac{x ^{2}}{15} + \frac{y ^{2}}{16} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{( 15 ) ^{2}} + \frac{( y - 0 ) ^{2}}{4 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 15, b = 4

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 4, a = 15

\frac{x ^{2}}{5} + \frac{y ^{2}}{4} = 1

64 x^{2} + 49 y^{2} = 3136

\frac{x ^{2}}{49} + \frac{y ^{2}}{64} = 1

4 x^{2} + 25 y^{2} + 40 x - 150 y + 225 = 0

4 (x - 5)^{2} + 9 (y + 2)^{2} = 36
