蝶を描くのに用いた関数
☆バタフライ曲線☆
極座標（ｒ、θ）で、原点Oから曲線までの距離をr,直線rとx軸のなす角をθとし、
r=±a∗√(2∗cos(θ))
として定義された関数がパラメトリック方程式で定義される曲線の一種であるバタフライ曲線です。
以下の式で媒介変数にして実行させました。
X(t)=sin(t)*|e^(cos(t))-2∗cos(4∗t)-（sin(1/12∗t)）^5|
Y(t)=cos(t)*|e^(cos(t))-2∗cos(4∗t)-（sin(1/12∗t)）^5|
雲を描くのに用いた関数
☆楕円☆
雲はおなじみの楕円を繋げて描きました。
媒介変数表示にした式を用いて、MAT PLOT AREAで塗りつぶしできるようにしました。

DRAW kumo WITH SHIFT(-10,15) SHIFT文でずらして楕円を連結させて雲を描いています
☆アステロイド曲線☆
これは蝶の触覚部分に用いました。
以下の式で媒介変数にして実行させました。
A(t)=（cos(t)）^3∗1.5+2.5
B(t)=（sin(t)）^3∗1.5+2.5
