((x-1)^2)/4+(y^2)/9 =1

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

(h, k) = (1, 0), a = 2, b = 3

Solution steps

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

Rewrite

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

in the form of the standard ellipse equation

\frac{( x - 1 ) ^{2}}{2 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (1, 0), a = 2, b = 3

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, 0), b = 3, a = 2

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

\frac{8 y}{1 + x ^{2} + y ^{2}} = 2

\frac{x ^{2}}{9} + \frac{y ^{2}}{7} = 1

\frac{y ^{2}}{a ^{2}} + \frac{x ^{2}}{b ^{2}} = 1

2 x^{2} + 8 y^{2} = 50
