Q. Given the reference angle of 132π, find the corresponding angle in Quadrant 3.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. Quadrant 3 is where both x and y coordinates are negative. To find an angle in Quadrant 3 with a given reference angle, we add π to the reference angle.
Calculate angle: Calculate the corresponding angle in Quadrant 3.The reference angle is (2π)/(13). To find the corresponding angle in Quadrant 3, we add π to the reference angle:Angle in Quadrant 3 = Reference Angle + πAngle in Quadrant 3 = (2π)/(13)+π
Simplify expression: Simplify the expression to find the exact angle.To add the angles, we need a common denominator. Since π is the same as (13π)/(13), we can write:Angle in Quadrant 3 = (2π)/(13)+(13π)/(13)Angle in Quadrant 3 = (2π+13π)/(13)Angle in Quadrant 3 = (15π)/(13)
