WebTranscribed Image Text: SECTION 1: Knowledge/Understanding 1. a) When using the unit circle to find the trigonometric ratios for 150°, a reference angle of 30° is used. Construct a unit circle to find the exact trigonometric ratios for 225°. WebUnit Circle. A unit circle has a center at (0, 0) and radius 1. In a unit circle, the length of the intercepted arc is equal to the radian measure of the central angle t. Let (x, y) be the endpoint on the unit circle of an arc of arc lengths. The (x, y) coordinates of this point can be described as functions of the angle.
WebThe unit circle is the circle whose center is at the origin and whose radius is one. The circumfrence of the unit circle is 2Π. An arc of the unit circle has the same length as the measure of the central angle that intercepts that arc. Also, because the radius of the unit circle is one, the trigonometric functions sine and cosine have special ... WebNov 3, 2024 · A “unit” circle has a radius of 1. In other words, the distance from the center of the circle to any part of the edge is always 1. The unit of measurement doesn’t really …
