UNIT CIRCLE TRIGONOMETRY. The Unit Circle is the circle centered at the origin with radius 1 unit (hence, the “unit” circle). The equation of this circle is x. 2. y. 2 = 1 . A diagram of the unit circle is shown below: We have previously applied trigonometry to triangles that were drawn with no reference to any coordinate system.
The coordinates for the _____ degree angle and _____ degree angle on the Unit Circle were derived by using the ___________________ Rule for right triangles. Find a positive coterminal angle for each of the following special angles on the unit circle :
2, (0, 900 2700 3n -1) 1) 2n 120' 5 n 1350 150' 1800 2106 2250 5 n 2400 (0, 300 3300 3150 3000 7n 517 4 n
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.
