1.a quarter of a circle; an arc of 90°. 2.the area included between such an arc and two radii drawn one to each extremity. 3.something shaped like a quarter of a circle, as a part of a machine. 4.one of the four parts into which a plane, as the face of a heavenly body, ...
The coordinate of the point (7, -4) are positive on the x-axis and negative on the y-axis, thus it lies in the 4th quadrant. Q.2: Give an example of a point that lies in the third quadrant. Solution: In the third quadrant, the coordinates of the x-axis and y-axis are both ...
Find the opposite side of the unit circletriangle. Since the adjacent side and hypotenuse are known, use the Pythagorean theorem to find the remaining side. ( (Opposite)=-√(((hypotenuse))^2-((adjacent))^2)) Replace the known values in the equation. ( (Opposite)=-√(((3))^2-(...

Answer to: Graph a circle with a radius of 2 and shade the first quadrant of the circle. Make sure you mark your scales. By signing up, you'll get...
(θ). Also, note that some of the identities have a±in front. The sign of the half-angle determines this sign, so it is important to know the, as in what functions are positive in what quadrant. The simplest way is to put the unit circle on top of the coordinate plane. Cosine ...
4 = 200.96/ 4 = 50.24 cm 2 frequently asked questions on area of quadrant q1 what is the quadrant of a circle? the quadrant of a circle is one-fourth of the circle. q2 what is the area of the quadrant? for the area of a quadrant, divide the area of a circle by 4 (as four ...
In which Quadrant is -570 degrees?Negative Angles in a Unit Circle:In trigonometry, when moving along the unit circle, positive angles are measured counter-clockwise and negative angles are measured clockwise from the origin. A similar convention is used for angles in polar coordinates....
