If the focal distance of an end of minor axis of any
\( \mathrm{P} \) ellipse, (whose axes along the \( x \) and \( y \) axes
W respectively is \( k \) and the distance between the foci is \( 2 h \). Then the equation of the ellipse is:
(1) \( \frac{x^{2}}{h^{2}}+\frac{y^{2}}{k^{2}}=1 \)
(2) \( \frac{x^{2}}{k^{2}}+\frac{y^{2}}{k^{2}-h^{2}}=1 \)
(3) \( x^{2}+\frac{y^{2}}{k^{2}}=1 \)
(4) \( \frac{x^{2}}{h^{2}}+y^{2}=1 \)
