Q. Given the reference angle of 133π, find the corresponding angle in Quadrant 2.Answer:
Concept Explanation: 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. The corresponding angle in Quadrant 2 is found by subtracting the reference angle from π, because angles in Quadrant 2 have values between 2π and π.
Calculate Angle: Calculate the corresponding angle in Quadrant 2.The corresponding angle θ in Quadrant 2 for a reference angle of 133π is given by π−133π.
Subtraction: Perform the subtraction to find the exact value. θ=π−133π=1313π−133π=1310π
Verification: Verify that the calculated angle is indeed in Quadrant 2.Since (10π)/(13) is greater than π/2 and less than π, it is in Quadrant 2.
