From there, you simply need algebra and a calculator that works in radians.
Take the inverse cos of both sides to get 2x = arccos(-1)
Then divide both sides by 2 to get x = arccos(-1) / 2
Put that into a calculator and you get π/2. But because your bounds are 0 to 2π, you have to add π your solution to get the solution on the other side of the unit circle, which would be (3π/2).
Now that you have the x value, put (π/2) and (3π/2) into f(x) to get the y coordinate.
f(π/2) = 2(π/2) + sin(2(π/2) = π, which means this solution is just (π/2, π)
f(3π/2 = 2(3π/2) + sin(2(3π/2) = 3π, which means this solution is (3π/2, 3π)
Answer:
In this order from top to bottom, you get -12, -8, 0, 6, and 8
Step-by-step explanation:
You simply plug in the X value into each equation where it is needed.
So for the first one
2(-5)-2 = -10-2 = -12
2(-3)-2 = -6-2 = -8
2(1)-2 = 2-2 = 0
2(4)-2 = 8-2 = 6
2(5)-2 = 10-2 = 8
