Q. Find the reference angle for a rotation of 114π.Answer:
Understand reference angle: Understand the concept of a reference angle. A reference angle is the acute angle formed by the terminal side of an angle in standard position and the x-axis. It is always between 0 and π/2 radians (or 0 and 90 degrees) and is positive.
Determine angle quadrant: Determine the quadrant in which the angle (4π)/(11) radians lies.Since (4π)/(11) is less than π (which is approximately 3.14), the angle lies in the first quadrant where the reference angle is the same as the angle itself.
Calculate reference angle: Calculate the reference angle for (4π)/(11) radians when the angle is in the first quadrant.The reference angle θ′ is equal to θ when θ is in the first quadrant. Therefore, θ′=(4π)/(11) radians.
