29= 1/2 (5.6)(7.1)sin(x)

解答

29 = \frac{1}{2} (5.6) (7.1) sin (x)

解答

x \in R 无解

求解步骤

29 = \frac{1}{2} (5.6) (7.1) sin (x)

交换两边

\frac{1}{2} \cdot 5.6 \cdot 7.1 sin (x) = 29

化简

\frac{1}{2} \cdot 5.6 \cdot 7.1 : \frac{39.76}{2}

\frac{1}{2} \cdot 5.6 \cdot 7.1

数字相乘:

5.6 \cdot 7.1 = 39.76

= 39.76 \cdot \frac{1}{2}

分式相乘:

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

= \frac{1 \cdot 39.76}{2}

数字相乘:

1 \cdot 39.76 = 39.76

= \frac{39.76}{2}

\frac{39.76}{2} sin (x) = 29

在两边乘以

2

\frac{39.76}{2} sin (x) = 29

在两边乘以

2

2 \cdot \frac{39.76}{2} sin (x) = 29 \cdot 2

化简

39.76 sin (x) = 58

39.76 sin (x) = 58

两边除以

39.76

39.76 sin (x) = 58

两边除以

39.76

\frac{39.76 sin ( x )}{39.76} = \frac{58}{39.76}

化简

sin (x) = 1.45875 \dots

sin (x) = 1.45875 \dots

- 1 \leq sin (x) \leq 1

x \in R 无解

(10.4)/(sin(x))=(12)/(sin(62))

\frac{10.4}{sin ( x )} = \frac{12}{sin ( 6 2 ^{\circ} )}

csc(θ)=-2,0<= θ<= 360

csc (θ) = - 2, 0^{\circ} \leq θ \leq 36 0^{\circ}

sin (B) = \frac{12}{13}

csc (x - 4 5^{\circ}) = 2

- 5 sin (2 t) = 0
