solvefor x,csin(mx)m=(npi)/a

解答

求解

x, c sin (m x) m = \frac{nπ}{a}

解答

x = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}, x = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}

求解步骤

c sin (m x) m = \frac{nπ}{a}

两边除以

c m; c \neq = 0

c sin (m x) m = \frac{nπ}{a}

两边除以

c m; c \neq = 0

\frac{c sin ( m x ) m}{c m} = \frac{\frac{nπ}{a}}{c m}; c \neq = 0

化简

\frac{c sin ( m x ) m}{c m} = \frac{\frac{nπ}{a}}{c m}

化简

\frac{c sin ( m x ) m}{c m} : sin (m x)

\frac{c sin ( m x ) m}{c m}

约分:

c

= \frac{m sin ( m x )}{m}

约分:

m

= sin (m x)

化简

\frac{\frac{nπ}{a}}{c m} : \frac{πn}{c ma}

\frac{\frac{nπ}{a}}{c m}

使用分式法则:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{nπ}{a c m}

sin (m x) = \frac{πn}{c ma}; c \neq = 0

sin (m x) = \frac{πn}{c ma}; c \neq = 0

sin (m x) = \frac{πn}{c ma}; c \neq = 0

使用反三角函数性质

sin (m x) = \frac{πn}{c ma}

sin (m x) = \frac{πn}{c ma}

的通解

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

m x = arcsin (\frac{πn}{c ma}) + 2 πk, m x = π + arcsin (- \frac{πn}{c ma}) + 2 πk

m x = arcsin (\frac{πn}{c ma}) + 2 πk, m x = π + arcsin (- \frac{πn}{c ma}) + 2 πk

解

m x = arcsin (\frac{πn}{c ma}) + 2 πk : x = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

m x = arcsin (\frac{πn}{c ma}) + 2 πk

两边除以

m; m \neq = 0

m x = arcsin (\frac{πn}{c ma}) + 2 πk

两边除以

m; m \neq = 0

\frac{m x}{m} = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

化简

x = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

x = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

解

m x = π + arcsin (- \frac{πn}{c ma}) + 2 πk : x = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

m x = π + arcsin (- \frac{πn}{c ma}) + 2 πk

两边除以

m; m \neq = 0

m x = π + arcsin (- \frac{πn}{c ma}) + 2 πk

两边除以

m; m \neq = 0

\frac{m x}{m} = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

化简

x = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

x = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}; m \neq = 0

x = \frac{arcsin ( \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}, x = \frac{π}{m} + \frac{arcsin ( - \frac{πn}{c ma} )}{m} + \frac{2 πk}{m}

6 tan (x) = 4

3tan(x)+cot(x)-5csc(x)=0

3 tan (x) + cot (x) - 5 csc (x) = 0

3cos^2(x)=1-5sin(x)

3 cos^{2} (x) = 1 - 5 sin (x)

solvefor x,2sin(3x)-1=0
