Find 4 solutions (in radians) of sine = 0.18.
1 answer:
9514 1404 393
Answer:
0.180986, 2.96061, 6.46417, 9.24379
Step-by-step explanation:
The first solution to ...
sin(x) = 0.18
is found by using the arcsine function:
x = arcsin(0.18) ≈ 0.180986
Additional positive values can be found by subtracting this angle from π, and by adding multiples of 2π to either of the values obtained so far.
π - 0.180986 ≈ 2.96061
Adding 2π to these gives two more values:
0.180986 +2π ≈ 6.46417
2.96061 +2π ≈ 9.24379

Answer:
The points are (-1, 1), (2, 7), (1, -1), (3, 0)
Step-by-step explanation:
Let us solve the question
∵ f(x) = y
∴ The coordinates of the point are (x, y)
→ Let us use this fact to find the coordinates of each point
∵ f(-1) = 1
∴ x = -1 and y = 1
∴ The coordinates of the point are (-1, 1)
∵ f(2) = 7
∴ x = 2 and y = 7
∴ The coordinates of the point are (2, 7)
∵ f(1) = -1
∴ x = 1 and y = -1
∴ The coordinates of the point are (1, -1)
∵ f(3) = 0
∴ x = 3 and y = 0
∴ The coordinates of the point are (3, 0)
