student[intercept] - 2 曲線の交点を求めます
使い方
intercept(eqn1)
intercept(eqn1, eqn2, {x, y})
パラメータ
eqn1, eqn2 - 2 変数の方程式 (例えば y = x^2 + 3)
x, y - 座標変換 (オプション)
説明
eqn1 and eqn2 で定義された 2 曲線の交点に対応する点を求めます。
方程式が 1 つしか指定されなかったときは、y 切片 (x = 0 との交点) が戻ります。この場合、y = 3*x + 5 のように、左辺に独立変数が 1 つだけあるような方程式を指定する必要があります。.
3 番目の引数は省略可能で、座標の変数を指定するために使用します。
with(student,intercept) を実行すると, このコマンドのみを定義できます。
例
with(student): intercept(y = x+5);
intercept(y = x+5, y = 0);
intercept(y+4 = x+5, x = 0);
intercept(y = a*x+b, x = 0, {x, y});
