Assertion: circle's equation | /r/CapableOf | hold for point
Facets:
value: on the unit circle
type: LOCATION
value: since x2
type: TEMPORAL
Source sentences:
text: Since x2 = (−x)2 for all x, and since the reflection of any point on the unit circle about the x- or y-axis is also on the unit circle, the above equation holds for all points (x, y) on the unit circle, not only those in the first quadrant.
text: x and y satisfy the equation Since x² = ² for all x, and since the reflection of any point on the unit circle about the x- or y-axis is also on the unit circle, the above equation holds for all points on the unit circle, not only those in the first quadrant.
