Find the Quadrant of the Angle (3pi)/2
Problem
Solution
Identify the angle in radians. The given angle is
(3*π)/2 Convert the angle to degrees if necessary to visualize its position. Since
π radians is180 we calculate(3⋅180)/2=270 Determine the boundary positions of the quadrants. Quadrant I is
0<θ<π/2 Quadrant II isπ/2<θ<π Quadrant III isπ<θ<(3*π)/2 and Quadrant IV is(3*π)/2<θ<2*π Conclude the location of the angle. Because the angle is exactly
(3*π)/2 (or270 , it lies exactly on the negative y-axis. Angles that fall on the axes are called quadrantal angles and do not belong to any specific quadrant.
