solvefor y,(x-h)^2+(y-k)^2=r^2

解

解く

y, (x - h)^{2} + (y - k)^{2} = r^{2}

解

y = r^{2} - x^{2} + 2 h x - h^{2} + k, y = - r^{2} - x^{2} + 2 h x - h^{2} + k

解答ステップ

(x - h)^{2} + (y - k)^{2} = r^{2}

(x - h)^{2}

を右側に移動します

(y - k)^{2} = r^{2} - (x - h)^{2}

簡素化

r^{2} - (x - h)^{2} : r^{2} - x^{2} + 2 h x - h^{2}

(g (x))^{2} = f (a)

の場合, 解は

g (x) = f (a), - f (a)

解く

y - k = r^{2} - x^{2} + 2 h x - h^{2} : y = r^{2} - x^{2} + 2 h x - h^{2} + k

解く

y - k = - r^{2} - x^{2} + 2 h x - h^{2} : y = - r^{2} - x^{2} + 2 h x - h^{2} + k

二次equationの解:

y = r^{2} - x^{2} + 2 h x - h^{2} + k, y = - r^{2} - x^{2} + 2 h x - h^{2} + k
