29.19sin(x)=1.5406

解答

2 \cdot 9.19 \cdot sin (x) = 1.5406

解答

x = 0.08391 \dots + 2 πn, x = π - 0.08391 \dots + 2 πn

+1

度数

x = 4.80813 \dots^{\circ} + 36 0^{\circ} n, x = 175.19186 \dots^{\circ} + 36 0^{\circ} n

求解步骤

2 \cdot 9.19 sin (x) = 1.5406

两边除以

18.38

2 \cdot 9.19 sin (x) = 1.5406

两边除以

18.38

\frac{2 \cdot 9.19 sin ( x )}{18.38} = \frac{1.5406}{18.38}

化简

sin (x) = \frac{1.5406}{18.38}

sin (x) = \frac{1.5406}{18.38}

使用反三角函数性质

sin (x) = \frac{1.5406}{18.38}

sin (x) = \frac{1.5406}{18.38}

的通解

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

x = arcsin (\frac{1.5406}{18.38}) + 2 πn, x = π - arcsin (\frac{1.5406}{18.38}) + 2 πn

x = arcsin (\frac{1.5406}{18.38}) + 2 πn, x = π - arcsin (\frac{1.5406}{18.38}) + 2 πn

以小数形式表示解

x = 0.08391 \dots + 2 πn, x = π - 0.08391 \dots + 2 πn

csc^3(x)-4csc(x)=3cot^2(x)

csc^{3} (x) - 4 csc (x) = 3 cot^{2} (x)

1+tan^2(θ)=4tan^2(θ)

1 + tan^{2} (θ) = 4 tan^{2} (θ)

(tan(θ)+1)(cos(θ)+1)(sin(θ))=0

(tan (θ) + 1) (cos (θ) + 1) (sin (θ)) = 0

6 sin (2 x) - 3 = 0

4cos^2(x)-sin(x)=1

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