\( c^2 \;=\; a^2 - b^2 \)
Symbol
English
Metric
\( c \) = length center to focus
\( in \)
\( mm \)
\( a \) = length semi-major axis
\( in \)
\( mm \)
\( b \) = length semi-minor axis
\( in \)
\( mm \)
Foci is a point used to define the conic section. F and G seperately are called "focus", both togeather are called "foci".
