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:
Somewhere in my car
Step-by-step explanation:
i know the song and im also just doing this for points so yeah
=3.5:17
3.5×10 to remove decimal point then u multiply 17 by 10 too
=35:170
then you simply yo get 7:34
Then 2 is greater than 3 (>)
9-(.5)^(4)/48
= 9-0.0013020833
=8.9986
