-1=x^2+y^2

Solution

- 1 = x^{2} + y^{2}

Solution

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

Solution steps

- 1 = x^{2} + y^{2}

Rewrite

- 1 = x^{2} + y^{2}

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

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

Popular Examples

(x^2)/9+(y^2)/(20)=1

\frac{x ^{2}}{9} + \frac{y ^{2}}{20} = 1

(x^2+y^2+8y-16)/(x^2+y^2+8y+16)=9

\frac{x ^{2} + y ^{2} + 8 y - 16}{x ^{2} + y ^{2} + 8 y + 16} = 9

5x^2-30x+9y^2-3y+36=0

5 x^{2} - 30 x + 9 y^{2} - 3 y + 36 = 0

2x^2-9x+4y^2+8x=16

2 x^{2} - 9 x + 4 y^{2} + 8 x = 16

20 x^{2} + 9 y^{2} = 225
