solvefor y,x=2sec(y)

解答

求解

y, x = 2 sec (y)

解答

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

求解步骤

x = 2 sec (y)

交换两边

2 sec (y) = x

两边除以

2

2 sec (y) = x

两边除以

2

\frac{2 sec ( y )}{2} = \frac{x}{2}

化简

sec (y) = \frac{x}{2}

sec (y) = \frac{x}{2}

使用反三角函数性质

sec (y) = \frac{x}{2}

sec (y) = \frac{x}{2}

的通解

sec (x) = a \Rightarrow x = arcsec (a) + 2 πn, x = - arcsec (a) + 2 πn

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

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

流行的例子

tan (π + c) = 1

8sin^2(x)=8cos^2(x)

8 sin^{2} (x) = 8 cos^{2} (x)

sin (x) = \frac{6}{8}

tan(x)=2+tan(3x)

tan (x) = 2 + tan (3 x)

2 sin (x) - 3 = 0
