6cot(x)+5=-1

解答

6 cot (x) + 5 = - 1

解答

x = \frac{3 π}{4} + πn

+1

度数

x = 13 5^{\circ} + 18 0^{\circ} n

求解步骤

6 cot (x) + 5 = - 1

将

5

到右边

6 cot (x) + 5 = - 1

两边减去

5

6 cot (x) + 5 - 5 = - 1 - 5

化简

6 cot (x) = - 6

6 cot (x) = - 6

两边除以

6

6 cot (x) = - 6

两边除以

6

\frac{6 cot ( x )}{6} = \frac{- 6}{6}

化简

cot (x) = - 1

cot (x) = - 1

cot (x) = - 1

的通解

cot (x)

11csc(x)+15=9csc(x)+19

11 csc (x) + 15 = 9 csc (x) + 19

sin^2(x)=(tan(x))/2

sin^{2} (x) = \frac{tan ( x )}{2}

((sin(x)+tan(x)))/(1+cos(x))=m*sec(x)

\frac{( sin ( x ) + tan ( x ) )}{1 + cos ( x )} = m \cdot sec (x)

2sin(2x)-2sin(x)=0

2 sin (2 x) - 2 sin (x) = 0

(sin(25))/5 =(sin(b))/8

\frac{sin ( 2 5 ^{\circ} )}{5} = \frac{sin ( b )}{8}
