Q. Given the reference angle of 7π, find the corresponding angle in Quadrant 2.Answer:
Concept of Reference Angles: 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, since angles in Quadrant 2 have values between 2π and π.
Calculate Angle in Quadrant 2: Calculate the corresponding angle in Quadrant 2. The corresponding angle in Quadrant 2, θ2, is given by θ2=π−(π/7).
Perform Subtraction for Exact Value: Perform the subtraction to find the exact value. θ2=π−(π/7)=(7π/7)−(π/7)=(6π/7).
