Q. Given the reference angle of 73π, find the corresponding angle in Quadrant 4.Answer:
Understand Reference Angle: To find the corresponding angle in Quadrant 4, we need to understand that the reference angle is the acute angle that the terminal side of an angle makes with the x-axis. In Quadrant 4, the angle is measured from the positive x-axis to the terminal side in a clockwise direction. Since the full circle is 2π radians, the angle in Quadrant 4 will be 2π minus the reference angle.
Calculate Angle in Quadrant 4: Calculate the corresponding angle in Quadrant 4 by subtracting the reference angle from 2π.Corresponding angle in Quadrant 4 = 2π−(73π)
Perform Subtraction: Perform the subtraction to find the exact value.Corresponding angle in Quadrant 4 = (14π/7)−(3π/7)=(11π/7)
