What is an interval in math term?
An interval is a subset of an order-numbered set; the interval includes a highest- numbered member of the subset and a lowest-numbered member of the subset and all members of the set with order numbers with values between that of the highest- and lowest-numbered members. This is more exactly called a "closed interval". An "open interval" is defined in the same way, except that the lowest-numbered and highest-numbered limits are not part of the subset.
What is the meaning abbreviation am?
If you are asking about time-related A M and P M then it means - Ante meridian and post meridian. "Ante" is Latin for "before", "post" means after.Meridian is when the sun reaches its zenith, the highest point in its daily arc; i.e., noontime.
Am and pm mean?
AM = "Ante - Meridian"PM = "Post - Meridian""Ante" and "post" mean "before" and "after"."Meridian" is the imaginary line in the sky that runs north/south and passes directly over you.In the morning, the sun moves from the eastern horizon toward the meridian. At Noon, the sun crosses the meridian. In the afternoon, the sun has crossed the meridian and moves away from it toward the west.Morning is the time before the sun crosses the meridian = Ante-Meridian = AM.Afternoon and evening is the time after the sun crosses the meridian = Post-Meridian = PM.
How many degrees are there longitudinal?
There are 360 degrees. They are numbered 0, 1-179 East, 180, and 1-179 West.360 degrees.On the earth, there is the Greenwich Meridian = 0 deg;1 - 179 East and 1 - 179 West;and 180 deg, much of which forms the International Date Line.
What is ante-meridian?
Time before noon. Before the use of standard time, (Greenwich Mean Time, time zones, etc.) most communities used solar time. Every town had its own standard of time. Noon was when the sun reached its highest point in the sky on any given day. Solar noon happens at the moment of the sun's transit of the meridian; the geographical north- south imaginary line directly overhead that the sun and other celestial bodies cross. Before the sun crosses the meridian it is morning. After the sun crosses the meridian it is afternoon (post meridian). In modern times we still use the a.m. and p.m. designations, even though they are not technically correct.
