solvefor x,(Y(x)^2)/(4-x^2)=1

解答

求解

x, \frac{Y ( x ) ^{2}}{4 - x ^{2}} = 1

x = \frac{2}{Y + 1}, x = - \frac{2}{Y + 1}; Y \neq = - 1

求解步骤

\frac{Y x ^{2}}{4 - x ^{2}} = 1

在两边乘以

4 - x^{2}

x^{2} Y = 4 - x^{2}

解

x^{2} Y = 4 - x^{2} : x = \frac{2}{Y + 1}, x = - \frac{2}{Y + 1}; Y \neq = - 1

x = \frac{2}{Y + 1}, x = - \frac{2}{Y + 1}; Y \neq = - 1

\frac{y ^{2}}{16} = 1 - \frac{x ^{2}}{9}

4 x^{2} + 9 y^{2} + 16 x - 36 y + 16 = 0

- 16 - x^{2} - y^{2} \geq 0

\frac{( x - 2 ) ^{2}}{9} + \frac{( y - 1 ) ^{2}}{36} = 1

\frac{( x - 3 ) ^{2}}{16} + \frac{( y + 2 ) ^{2}}{25} = 1
