Latitude latitude, to avoid ambiguity with the geodetic latitude and the auxiliary latitudes defined in subsequent sections of this article. Besides the equator, four other parallels are of significance: The plane of the Earth's orbit about the Sun is called the ecliptic, and the plane perpendicular to the rotation axis of the Earth is the equatorial plane. The angle between the ecliptic and the equatorial plane is called variously the axial tilt, the obliquity, or the inclination of the ecliptic, and it is conventionally denoted by . The latitude of the tropical circles is equal to and the latitude of the
Dell Latitude the Latitude line (due to switching to a USB C/Thunderbolt dock system, rather than the e-Port analog pin-system docks), and the models just go by number now, e.g.: Latitude 5480, 5570. The second number in the model (As in, 5470 or 7280) indicates the size of the screen in the laptop. The current Dell Latitude lineup is as follows: Latitude 3xxx series. Budget models intended for education or home office environments, available in 13.3"/14"/15.6" trims. Latitude 5xxx series. Mainstream line, available in 11.1"/12.5"/13.3"/14"/15.6" trims. Latitude 7xxx series. Premium "ultrabooks", available in 12.5"/13.3"/14" trims only. Latitude computers are also differentiated in
