The distance along one degree of longitude is 60 nautical miles at the equator and less at latitudes away from the equator. In fact it is 60 nautical miles times the cosine of the latitude, so 60 at the equator zero at the poles, and 30 nautical miles at 60 degrees north or south..

How many kilometer are in one complete rotation?
The number of kilometers in each full rotation of Earth depends on your latitude. Actually, it's the entire length of your latitude, which is roughly 40,075 km times the cosine of your latitude.
How fast does the earth spin in kilometers?
A point on the Earth's surface moves at approximately(1,670 kilometers per hour) x (cosine of its latitude).-- 1,670 kilometers per hour on the equator.-- 1,446 kilometers per hour at 30° latitude-- 1,181 kilometers per hour at 45° latitude-- 835 kilometers per hour at 60° latitude-- 432 kilometers per hour at 75° latitude-- zero at the poles
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
How many miles is a line of latitude?
-- Since every point on a line of latitude has the same latitude, the line has no thickness. -- Its length depends on its latitude. -- The line at zero latitude, known as the 'equator', is a great circle and so its length is the circumference of the Earth ... about 24,900 miles. -- Every other line of latitude is a small circle. Its length is 24,900 miles times the cosine of the latitude which it marks. -- The distance between any latitude and the one that's 1° north or south of it is about 111.1 kilometers (69 miles).
What is the derivation of the wave function?
A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
What is the form for finding cosine in fraction form?
Cosine = Adjacent/hypotenuse
What is the equation for finding the sine and cosine and tangent of a triangle?
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
How many kilometer are in one complete rotation?
The number of kilometers in each full rotation of Earth depends on your latitude. Actually, it's the entire length of your latitude, which is roughly 40,075 km times the cosine of your latitude.
What is cosine cubed?
It is cosine*cosine*cosine.
What is distance measured in degrees east or west of the prime meridian?
The Prime Meridian is defined as zero degrees of longitude. The distance in miles between degrees of longitude depends on the latitude; one degree of longitude equals the cosine of the latitude * 60 nautical miles. Note: If you're using Excel or some other spreadsheet program, be sure to convert degrees into radians before calculating the cosine of the latitude.
How many nautical miles in one minute of longitude?
60 at the equator, decreasing steadily to zero at the poles. In general: (60) times (the cosine of the latitude).
The inverse of the cosine function?
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.

How far is it around the world at 38 degrees north latitude?
That would be the equatorial circumference times the cosine of 38 degrees. I get 19,605 miles (31,552 km) .
How far is geographic second?
In latitude, 1 second is equivalent to roughly 30.8 meters. In latitude, 1 second is equivalent to roughly 30.8 meters along the equator, and it shrinks steadily to zero at the poles. In general, it's 30.8 meters multiplied by the cosine of the latitude where it's being measured.
What is cosine of 1?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
