WebPrecalculus questions and answers. Find the reference angle, the quadrant of the terminal side, and the sine and cosine of 225°. Enter the exact answers. The terminal side of the angle 225° lies in quadrant Click for List Its reference angle is Number ь sin (a BO @ sin (225°) = sin (225°) = ab sin (a) 00 a E COS (225°) =. WebLike all functions, the sine function has an input and an output. Its input is the measure of the angle; its output is the y -coordinate of the corresponding point on the unit circle. The cosine function of an angle t t equals the x -value of the endpoint on the unit circle of an arc of length t t. In Figure 3, the cosine is equal to x x.

WebArea of Quadrant. Area of quadrant is the space occupied by one-fourth part of a circle and is equal to one-fourth of the area of a circle. The formula for the area of a quadrant is 1/4 × area of a circle or is equal to πr 2 /4. And the units for area of quadrant is m 2, inch 2, cm 2.. Let us learn more about the area of quadrant, the formula of area of quadrant, … WebUsing tangent you get -x so you add 180, which is the same as 180 - x. -2i - 3j makes the same triangle in quadrant 3 where the relevant angle is 180 + x. So that means if you take the tangent of a vector in quadrant 2 or 3 you add 180 to that. If you have -2i - 3j then you have the same triangle in quadrant 4.
