Write the standard form of the equation of the ellipse whose orientation is along the vertical axis is,
The coordinate of the foci is
The vertices are at
The value of
The planet Halley’s Comet travels around the sun in elliptical orbit.
The aphelion of the elliptical orbit of the sun is
The diameter of the sun is
The length of major axis of the ellipse is the sum of aphelion, perihelion and sun’s diameter.
Simplify as,
The focus of the centre is the value of
To calculate the value of
The standard form of the equation at the given origin centre of the elliptical orbit of the planet Halley’s comet is,
Thus, the equation for the given ellipse is
