Q. Given the reference angle of 136π, find the corresponding angle in Quadrant 2.Answer:
Understand concept: Understand the concept of reference angles and quadrants.A reference angle is the acute angle formed by the terminal side of an angle and the x-axis. In Quadrant 2, the angles are between 2π and π. To find the corresponding angle in Quadrant 2 for a given reference angle, we subtract the reference angle from π.
Calculate angle: Calculate the corresponding angle in Quadrant 2.The reference angle is (6π)/(13). To find the corresponding angle in Quadrant 2, we subtract this reference angle from π:θ=π−(6π)/(13)
Perform subtraction: Perform the subtraction to find the angle in Quadrant 2.θ=1313π−136πθ=137π
Verify quadrant: Verify that the calculated angle is indeed in Quadrant 2.The angle (7π)/(13) is between π/2 and π, which confirms that it is in Quadrant 2.
