Teorema Butterfly Dan Double Butterfly Pada Parabola Dan Elips

This final project presents a proof of the butterfly and double butterfly theorems on parabola and ellipse using Haruki’s lemma. In addition, this final project also shows the use of modifications of Haruki’s lemma on a parabola and Haruki’s lemma on ellipse for each proof step.
