Unit Circle Quadrants Unit Circle Examples Lesson Summary Frequently Asked Questions What is a reference point on the unit circle? The unit circle is often shown on a coordinate plane with its center at the origin, with the distance from any point on the circle to the origin being 1, the...
The unit circle chart in radians is given in the diagram below. It represents a total angle of 2 radians or 360. The unit circle is divided into four quadrants by the intersection of x-axis and y-axis. The points which represent the angles $\frac{\pi}{0},\; \frac{\pi}{6},\; ...
In math we would call these four parts of the circle quadrants. Fig. 2. Unit circle with quadrants added. The first quadrant is top right, second quadrant is top left, third quadrant is bottom left and fourth quadrant is bottom right. © HowStuffWorks 2021 We can use (x, y) ...

Memorize the Four Quadrants You may notice there is fantastic symmetry on the unit circle. The circle is divided into four quadrants, each separated by a right angle, or 90 degrees. At each of the lines dividing the quadrants, one of the trig functions equals zero, and the other equals ei...
This is simplified to obtain the equation of a unit circle. Equation of a Unit Circle: x2 + y2 = 1 Here for the unit circle, the center lies at (0,0) and the radius is 1 unit. The above equation satisfies all the points lying on the circle across the four quadrants. Finding ...
a) Therefore, in which quadrants will sin θ -- y -- be positive? I and II.a) In which quadrants will sin θ be negative? III and IV.b) The algebraic sign of cos θ will always be the sign of which b) coördinate? x, because cos θ = x/r, and again, r is always...
