Formula Used by the Latus Rectum Calculator

The calculator uses different formulas depending on the conic section.

For a Parabola

If the equation is:

y² = 4ax

Then:

Length of Latus Rectum = 4a

For an Ellipse

If:

• Semi-major axis = a
• Semi-minor axis = b

Then:

Length of Latus Rectum = (2b²)/a

For a Hyperbola

If:

• Semi-transverse axis = a
• Semi-conjugate axis = b

Then:

Length of Latus Rectum = (2b²)/a

These formulas are applied automatically by the calculator, eliminating manual computation.
