solvefor x,z=sin(5x)y^3

解答

求解

x, z = sin (5 x) y^{3}

解答

x = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}, x = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

求解步骤

z = sin (5 x) y^{3}

交换两边

sin (5 x) y^{3} = z

两边除以

y^{3}; y \neq = 0

sin (5 x) y^{3} = z

两边除以

y^{3}; y \neq = 0

\frac{sin ( 5 x ) y ^{3}}{y ^{3}} = \frac{z}{y ^{3}}; y \neq = 0

化简

sin (5 x) = \frac{z}{y ^{3}}; y \neq = 0

sin (5 x) = \frac{z}{y ^{3}}; y \neq = 0

使用反三角函数性质

sin (5 x) = \frac{z}{y ^{3}}

sin (5 x) = \frac{z}{y ^{3}}

的通解

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

5 x = arcsin (\frac{z}{y ^{3}}) + 2 πn, 5 x = π + arcsin (- \frac{z}{y ^{3}}) + 2 πn

5 x = arcsin (\frac{z}{y ^{3}}) + 2 πn, 5 x = π + arcsin (- \frac{z}{y ^{3}}) + 2 πn

解

5 x = arcsin (\frac{z}{y ^{3}}) + 2 πn : x = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

5 x = arcsin (\frac{z}{y ^{3}}) + 2 πn

两边除以

5

5 x = arcsin (\frac{z}{y ^{3}}) + 2 πn

两边除以

5

\frac{5 x}{5} = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

化简

x = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

x = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

解

5 x = π + arcsin (- \frac{z}{y ^{3}}) + 2 πn : x = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

5 x = π + arcsin (- \frac{z}{y ^{3}}) + 2 πn

两边除以

5

5 x = π + arcsin (- \frac{z}{y ^{3}}) + 2 πn

两边除以

5

\frac{5 x}{5} = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

化简

x = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

x = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}

x = \frac{arcsin ( \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}, x = \frac{π}{5} + \frac{arcsin ( - \frac{z}{y ^{3}} )}{5} + \frac{2 πn}{5}
