[Verse]
The standard form
Of the equation
Of an ellipse
With the center at the origin
And the major axis horizontal

[Chorus]
X squared
Over A squared
Plus Y squared
Over B squared
Equals one
And the vertices
Plus or minus A, zero

[Verse]
The standard form
Of the equation
Of an ellipse
With the center at the origin
And the major axis vertical

[Chorus]
X squared
Over B squared
Plus Y squared
Over A squared
Equals one
And the vertices
Zero, plus or minus A
[Outro]
Co-vertices
Co-vertices
Co-vertices
Co-vertices
Co-vertices
Co-vertices...
