Ease of Calculation
Rational trigonometry makes some problems solvable with only addition, subtraction, multiplication, and division, with fewer uses of other functions such as square roots, sine, and cosine compared to classical trigonometry. Such algorithms execute more efficiently on most computers, for problems such as solving triangles. Other computations, however, do involve more computations than their classical analogues; such computations include determining the quadrance of a line segment given the quadrance of two collinear line segments which compose it, or such as computing the spread of the sum of two angles with known spreads.

Famous quotes containing the words ease of, ease and/or calculation:
“In England, I was quite struck to see how forward the girls are made—a child of 10 years old, will chat and keep you company, while her parents are busy or out etc.—with the ease of a woman of 26. But then, how does this education go on?—Not at all: it absolutely stops short.”
—Frances Burney (1752–1840)
“There the wicked cease from troubling, and there the weary are at rest. There the prisoners are at ease together; they do not hear the voice of the taskmaster. The small and the great are there, and the slaves are free from their masters.”
—Bible: Hebrew, Job 3:17-19.
“Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.”
—Henri-Frédéric Amiel (1821–1881)
