solvefor y,sin(x^2y^2)=x

解

解く

y, sin (x^{2} y^{2}) = x

解

y = \frac{arcsin ( x ) + 2 πn}{x}, y = - \frac{arcsin ( x ) + 2 πn}{x}, y = \frac{π + arcsin ( - x ) + 2 πn}{x}, y = - \frac{π + arcsin ( - x ) + 2 πn}{x}

解答ステップ

sin (x^{2} y^{2}) = x

三角関数の逆数プロパティを適用する

sin (x^{2} y^{2}) = x

以下の一般解

sin (x^{2} y^{2}) = x

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π + arcsin (a) + 2 πn

x^{2} y^{2} = arcsin (x) + 2 πn, x^{2} y^{2} = π + arcsin (- x) + 2 πn

x^{2} y^{2} = arcsin (x) + 2 πn, x^{2} y^{2} = π + arcsin (- x) + 2 πn

解く

x^{2} y^{2} = arcsin (x) + 2 πn : y = \frac{arcsin ( x ) + 2 πn}{x}, y = - \frac{arcsin ( x ) + 2 πn}{x}; x \neq = 0

x^{2} y^{2} = arcsin (x) + 2 πn

以下で両辺を割る

x^{2}; x \neq = 0

x^{2} y^{2} = arcsin (x) + 2 πn

以下で両辺を割る

x^{2}; x \neq = 0

\frac{x ^{2} y ^{2}}{x ^{2}} = \frac{arcsin ( x )}{x ^{2}} + \frac{2 πn}{x ^{2}}; x \neq = 0

簡素化

y^{2} = \frac{arcsin ( x )}{x ^{2}} + \frac{2 πn}{x ^{2}}; x \neq = 0

y^{2} = \frac{arcsin ( x )}{x ^{2}} + \frac{2 πn}{x ^{2}}; x \neq = 0

x^{2} = f (a)

の場合, 解は

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