quadrant
In mathematics, one of the four areas into which a plane is divided by a Cartesian coordinate system (x- and y-axis).
Ein Punkt mit zwei positiven Koordinaten liegt im ersten Quadranten.
A point with two positive coordinates lies in the first quadrant.
quadrant
A historical astronomical or nautical instrument in the shape of a quarter circle, used to measure angles, especially the altitude of celestial bodies.
Seefahrer nutzten früher einen Quadranten, um ihre Position auf dem Meer zu bestimmen.
Sailors used to use a quadrant to determine their position at sea.
quarter section
In general, a quarter of a circle or of a circular object or area.
Für die Dekoration wurde der Kuchen in vier Quadranten aufgeteilt, die unterschiedlich belegt wurden.
For the decoration, the cake was divided into four quarter sections, each with different toppings.
The word 'Quadrant' (quadrant) comes from the Latin word 'quadrans', which means 'a fourth part'. All meanings of the word have to do with the idea of a quarter.
Der Garten wurde in vier Quadranten mit unterschiedlichen Pflanzen aufgeteilt.
The garden was divided into four quadrants with different plants.
The context makes the meaning clear. In mathematics, people speak of 'Koordinaten' (coordinates) and 'Achsen' (axes). In history, it is about 'Instrumente' (instruments) and 'Seefahrt' (seafaring). In everyday language, it is often used with 'aufteilen' (to divide up).
Der Punkt P(3, -5) liegt im vierten Quadranten.
The point P(3, -5) lies in the fourth quadrant.
In mathematics, the four quadrants are numbered with Roman or Arabic numerals counterclockwise, starting at the upper right. You say that a point 'liegt im' (lies in the) first, second, third, or fourth quadrant.
Ein Punkt mit einer negativen x-Koordinate und einer positiven y-Koordinate liegt im zweiten Quadranten.
A point with a negative x-coordinate and a positive y-coordinate lies in the second quadrant.
sector
In geometry, Sektor is a part of a circle bounded by two radii and can vary in size. Quadrant, by contrast, refers to exactly one quarter of a circle. So Quadrant is the right word for a 90-degree angle; for other angles, only Sektor is suitable.
Der markierte Quadrant des Kreises hat einen Winkel von 90 Grad.
The marked quadrant of the circle has an angle of 90 degrees.
Der markierte Sektor des Kreises hat einen Winkel von 60 Grad.
The marked sector of the circle has an angle of 60 degrees.
