Polar Coordinates Polar Coordinates The coordinate system which depicts the points from the pole to the certain distance at a particular angle is known as “polar coordinates”. The positive horizontal axis in which that particular angle rotates is named as “polar axis”.

Polar Coordinates and Graphs The big ideas are that x = rcos theta, y = rsin theta, r^2 = x^2 + y^2, and tan theta = y/x. Several examples are shown, with coordinates (r, theta).

About Polaris Polaris, located almost exactly at the north celestial pole, the center of spin, stays in the same place, while stars farther away from the north celestial pole can be seen to move in a wider circle around Polaris as viewed from Earth during its daily rotation. Polaris actually lies just a short distance away from where Earth's axis points. Polaris is located about 1 degree off to the side of the north celestial pole, so Polaris does move a little, tracing a very small arc in the night sky, around which the other visible stars make wider circles.

What is a polar molecule? Polar means having electrical poles . The molecules in which the arrangement or geometry of the atoms is such that one end of the molecule has a positive electrical charge and the other side has a negative charge are called as polar molecules. Examples of polar molecules are Water (H2O) (Fig. 2.1a), Ammonia (NH3).

polarize To polarize is to divide. Something that's been polarized has been split into two sides that are so different, it seems as though they're from opposite ends of the earth — like the North Pole and the South Pole. Political parties have long been polarized by different views and approaches to government.

The history of the star: Polaris The history of the star: Polaris. Alpha (α) Ursa Minor, Polaris, is a star in the tip of the tail of the Little Bear. Its name comes to us from Latin Stella Polaris, meaning Pole Star. Polaris is our Pole star, situated at the north pole it never sets and as Wikipedia explains Polaris stands almost motionless on the sky, and all the stars of the Northern sky appear to rotate around it.

- The points in the polar coordinates are represented as `(r, theta).`. Conversion from rectangular to polar coordinates: For the conversion of the coordinates of the points in the rectangular coordinates (x,y) to the polar coordinates (r,theta) the following relations are used,`r = sqrt (x^2+y^2)` ; `theta = tan^-1(y/x)`.Back to Top.he points in the polar coordinates are represented as `(r, theta).`.

Polar Coordinates Mentor: The polar coordinate system has axes similar to the Cartesian system and a point like the origin except that it is called the pole. It also has a ray that extends horizontally through the pole called the polar axis.

Polar orbit Polar orbit. A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It therefore has an inclination of (or very close to) 90 degrees to the equator.

Latitude The geocentric latitude ψ is the complement of the polar angle θ in conventional spherical polar coordinates in which the coordinates of a point are P(r,θ,λ) where r is the distance of P from the centre O, θ is the angle between the radius vector and the polar axis and λ is longitude.

geodetic coordinates Geodetic Coordinates. the geographical latitude and longitude of a point on the earth’s surface, determined by means of geodetic measurement of the distance (mainly by the method of triangulation) and the bearing (azimuth) from several other points whose geographic coordinates are known.eodetic coordinates are calculated on the surface of a reference ellipsoid, which is a characterization of the shape and dimensions of the earth.

polarize Polarize is to force a something or someone to go in only one direction, or to cause people to divide into two very distinct groups. When a special microscope forces the transverse waves created by a light to be focused only in one direction, this is an example of when it polarizes.

Polarization From Wikipedia, the free encyclopedia. Polarization (also polarisation) is a property of some types of waves. Some waves have motion in another direction as well as the direction of the wave. In water, for instance, the wave will move across the water, but something on the surface of the water will move up and down.

- Coordinates of a point. from Latin: coordinare to set in order, arrange. A pair of numbers defining the position of a point on a two-dimensional plane. Try this Drag the point A. As you drag note the two numbers that define its position on the plane. The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located. The coordinates are written as an ordered pair as shown below.
