25 kwi 2024 · A unit circle is divided into four quadrants making an angle of 90°, 180°, 270°, and 360° (in degrees) or π/2, π. 3π/2, and 2π (in radians) respectively. An angle on a unit circle is always measured from the positive x-axis, with its vertex at the origin.
Unit Circle. The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here.
For the following exercises, find the reference angle, the quadrant of the terminal side, and the sine and cosine of each angle. If the angle is not one of the angles on the unit circle, use a calculator and round to three decimal places.
