This, and the inclination of the orbit being given, we have all the geometrical data necessary to compute the coordinates of the planet itself.
They not only indicate the height of the land, but also enable us to compute the declivity of the mountain slopes; and if minor features of ground lying between two contours - such as ravines, as also rocky precipices and glaciers - are indicated, as is done on the Siegfried atlas of Switzerland, they fully meet the requirements of the scientific man, the engineer and the mountain-climber.
To cover the special risks of mining, capital should earn a higher interest than in ordinary business, and if we assume that the sinking-fund be safely invested, we must compute the amortization on a lower basis than 5%.
Mathematically we have thus in all cases to compute present value on the basis of a deferred as well as a limited annuity.
When the length of a meteor's: course is known and the duration of its flight has been correctly estimated it is easy to compute the velocity in miles.
As the amount of ash varies very considerably in different coals, and stands in no relation to the proportion of the other constituents, it is necessary in forming a chemical classification to compute the results of analysis after deduction of the ash and hygroscopic water.
Divide the span L into any convenient number n of equal parts of length 1, so that nl = L; compute the radii of curvature R 1, R2, R3 for the several sections.
As An Example, Suppose It Were Required To Compute Easter For The Year 1840.
To Compute The Times Of The New Moons Which Determine The Commencement Of Successive Years, It Must Be Observed That In Passing From An Ordinary Year The New Moon Of The Following Year Is Deduced By Subtracting The Interval That Twelve Lunations Fall Short Of The Corresponding Gregorian Year Of 365 Or 366 Days; And That, In Passing From An Embolismic Year, It Is To Be Found By Adding The Excess Of Thirteen Lunations Over The Gregorian Year.
The Parsees compute time from the fall of Yazdegerd.
" For some think that they ought to fast only one day, some two, some more days; some compute their day as consisting of forty hours night and day; and this diversity existing among those that observe it is not a matter that has just sprung up in our times, but long ago among those before us."
But when definitive results as to the orbits are required, it is necessary to compute the perturbations produced by such of the major planets as have affected the motions of the body.
The third law enables us to compute the time taken by the radius vector to sweep over the entire area of the orbit, which is identical with the time of revolution.
If, with the changed velocity we again compute the elements they will be different from the former elements.
Consider Jedediah Buxton of Derbyshire, England, who in the 1700s was asked to compute the number one would get by doubling a farthing 139 times.
We compute the maximum amount of food the world can produce by beginning with total acres of land considered arable, but that is based on assumptions about the future of technology and agriculture.
