solvefor x,1-cos(x)=0

解答

求解

x, 1 - cos (x) = 0

解答

x = 2 πn

+1

度数

x = 0^{\circ} + 36 0^{\circ} n

求解步骤

1 - cos (x) = 0

将

1

到右边

1 - cos (x) = 0

两边减去

1

1 - cos (x) - 1 = 0 - 1

化简

- cos (x) = - 1

- cos (x) = - 1

两边除以

- 1

- cos (x) = - 1

两边除以

- 1

\frac{- cos ( x )}{- 1} = \frac{- 1}{- 1}

化简

cos (x) = 1

cos (x) = 1

cos (x) = 1

的通解

cos (x)

x = 0 + 2 πn

x = 0 + 2 πn

解

x = 0 + 2 πn : x = 2 πn

x = 0 + 2 πn

0 + 2 πn = 2 πn

x = 2 πn

x = 2 πn

流行的例子

sin (x) = 467

csc (x) = \frac{5}{3}

sin(B)=((240.68*sin(21.16)))/(207.91)

sin (B) = \frac{( 240.68 \cdot sin ( 21.1 6 ^{\circ} ) )}{207.91}

sin(φ)-cos(φ)=sin(φ)tan(φ)

sin (φ) - cos (φ) = sin (φ) tan (φ)

sqrt(2)tan(x)cos(x)=tan(x)

2 tan (x) cos (x) = tan (x)
