Answer:
(15°, 165°)
Step-by-step explanation:
Given the equation 6 sin2(x) = 3, we are to find the value of x that satisfies the equation in the interval [0, 2π]
Given
6 sin2(x) = 3,
Divide both sides by 6
6 sin2(x)/6 = 3/6
sin2(x) = 1/2
2x = sin^-1(0.5)
2x = 30°
x = 30°/2
x = 15°
Since sin is positive in the second quadrant, x2 = 180-15
x = 165°
Hence the values within the interval are 15 and 165.
(15°, 165°)

Step-by-step explanation:
Answer:
-0.2
Step-by-step explanation:
Sine and cosine are co-functions.
That means, cos(90-x)=sin(x) or sin(90-x)=cos(x).
So here since cos(90-x)=-0.2, then sin(x)=-0.2.
