A circle is a geometric object that has symmetry about the vertical and horizontal lines through its center. When the circle is a unit circle (of radius 1) centered on the origin of the x-y plane, points in the first quadrant can be reflected across the x- or y- axes (or both) to give points in the other quadrants.
That is, if the terminal ray of an angle intersects the unit circle in the first quadrant, the point of intersection reflected across the y-axis will give an angle whose measure is the original angle subtracted from the measure of a half-circle. Since the measure of a half-circle is π radians, the reflection of the angle π/6 radians will be the angle π-π/6 = 5π/6 radians.
Reflecting 1st-quadrant angles across the origin into the third quadrant adds π radians to their measure. Reflecting them across the x-axis into the 4th quadrant gives an angle whose measure is 2π radians minus the measure of the original angle.
This is because two angles are zero and top is a straight line, and a line is 180 degrees!
hopes this helps :)
Answer:
this answer has to be A because the libra of the pole goes west
Step-by-step explanation:
this answer has to be A because the libra of the pole goes west
The range will be all ur y values...just as the domain is all the x values
so ur range is {5,6 }...notice that even though they repeat, u only have to list them once
