WebIdentify reference angles for angles on the unit circle. Identify the ordered pair on the unit circle for reference angles. Use ordered pairs on the unit circle to determine trig function … WebAn ordered pair, as is typically meant in beginning algebra (though there are some more advanced meanings you'll get into later), is the x and y coordinates of a point, stated in that order. Thus, (3,4) is the ordered pair representing the point at x=3 and y=4. (4,3) is not the same, that is the point at x=4 and y=3.

How do you use the ordered pairs on a unit circle to …

WebMay 12, 2024 · Just remember that coordinates on the unit circle can be derived using: (x, y) = (cos A, sin A), where A is the measurement of the angle. In this case, A = 4π 3. Now, you can plug in A into (cos A, sin A) to find the x and y coordinates of the answer. Just make sure to set your calculator to radians, since 4π 3 is in radians. WebMar 10, 2024 · The equation of the unit circle, coming directly from the Pythagorean theorem, looks as follows: x^2+y^2=1 x2 + y2 = 1 Or, analogically: \sin^2 (\alpha) + \cos^2 … WebThe coordinate geometry uses ordered pairs to represent geometric figures and objects in an open space for visual comprehension.
