Find the reference angle for a rotation of (5pi)/(8). 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 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 (5π)/(8) radians lies. Since (5π)/(8) is greater than π/2 but less than π, the angle lies in the second quadrant.Calculate reference angle: Calculate the reference angle for (5π)/(8) radians. The reference angle is found by subtracting the angle from π (which is the total angle in the second quadrant) because the angle is in the second quadrant. Reference angle = π - (5π)/(8)Perform subtraction: Perform the subtraction to find the reference angle. Reference angle = (8π)/(8) - (5π)/(8) Reference angle = (3π)/(8)Verify correct range: Verify that the reference angle is in the correct range. The reference angle (3π)/(8) is between 0 and π/2 radians, which is the correct range for a reference angle.

Q. Find the reference angle for a rotation of

\frac{5 \pi}{8}

\newline

Answer:

\newline

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 and the x-axis. It is always between $0$ and $\pi/2$ radians (or $0$ and $90$ degrees) and is positive.
Determine angle quadrant: Determine the quadrant in which the angle $(5\pi)/(8)$ radians lies. $\newline$ Since $(5\pi)/(8)$ is greater than $\pi/2$ but less than $\pi$ , the angle lies in the second quadrant.
Calculate reference angle: Calculate the reference angle for $(5\pi)/(8)$ radians. $\newline$ The reference angle is found by subtracting the angle from $\pi$ (which is the total angle in the second quadrant) because the angle is in the second quadrant. $\newline$ Reference angle = $\pi - (5\pi)/(8)$
Perform subtraction: Perform the subtraction to find the reference angle. $\newline$ Reference angle = $(8\pi)/(8) - (5\pi)/(8)$ $\newline$ Reference angle = $(3\pi)/(8)$
Verify correct range: Verify that the reference angle is in the correct range. $\newline$ The reference angle $(3\pi)/(8)$ is between $0$ and $\pi/2$ radians, which is the correct range for a reference angle.
