definition
noun
Geometry, and its branch trigonometry , was the mathematics Indian astronomers used most frequently.
the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.
example
William's father wrote a number of successful textbooks on arithmetic, calculus and 'trigonometry' , which brought in a comfortable income for the family.
This work is really the first in history on 'trigonometry' as an independent branch of pure mathematics and the first in which all six cases for a right-angled spherical triangle are set forth.
Cavalieri also wrote on conic sections, 'trigonometry' , optics, astronomy, and astrology.
If you were a surveyor, you could measure angles and then use high-school 'trigonometry' to calculate distances.
Because of the clarity and care with which his elementary texts on analytic geometry and 'trigonometry' were written they are still in demand.
In fact without the aid of the sine function and 'trigonometry' it is hard to see how Hypsicles could have done better.
He would have an easier time teaching them 'trigonometry' than the triangle.
There he gave courses on astronomy, celestial mechanics, the differential and integral calculus, the theory of probability, geometry and 'trigonometry' .
Most of his papers are solutions to problems posed by Euler on spherical geometry, 'trigonometry' , series, differential geometry and differential equations.
He studied a lot of mathematics in his own time including 'trigonometry' , differential and integral calculus, and complex numbers long before he met these topics in his formal education.
Omar Khayyam, known chiefly in Europe as a poet, combined 'trigonometry' and approximation theory to solve algebraic equations using geometry.
My math class, 'trigonometry' , will probably be the hardest one.
Omar Khayyam combined the use of 'trigonometry' and approximation theory to provide methods of solving algebraic equations by geometrical means.
Moore wrote the sections on arithmetic, geometry, 'trigonometry' and cosmography while the sections on algebra, Euclid and navigation were written by Perkins.
Indians also added to our knowledge of even more complicated branches of mathematics such as 'trigonometry' and calculus.
Slowly Caroline turned more and more towards helping William with his astronomical activities while he continued to teach her algebra, geometry and 'trigonometry' .
He graduated in 1860 with an outstanding report, which mentioned in particular his exceptional skills in mathematics, in particular 'trigonometry' .
With an interest in 'trigonometry' , mathematical instruments, astronomy, and geography, Regiomontanus was in a good position to give a lead.
Geometry, and its branch 'trigonometry' , was the mathematics Indian astronomers used most frequently.
Lexell made major contributions to spherical geometry and 'trigonometry' .
Rather than using geometrical methods, as Ptolemy had done, al-Battani used 'trigonometrical' methods which were an important advance.
He studied algebras and published papers on 'trigonometrical' series.
Vallée Poussin also worked on approximation to functions by algebraic and 'trigonometric' polynomials from 1908 to 1918.
But there were algebraic, 'trigonometrical' , and simple Pythagorian solutions offered, too
The radian measure makes many 'trigonometric' equations simpler and so it is the preferred unit of measuring angles in mathematics.
Astronomy, time-keeping and geography provided other motivations for geometrical and 'trigonometrical' research.
Curves (such as the 'trigonometric' polynomials of elliptic Fourier analysis) may be fit to such an outline, and then compared through statistical analysis of their parameters.
It is perhaps surprising that the second most important 'trigonometrical' function during the period we have discussed was the versed sine, a function now hardly used at all.
However after this the centre of activity moved to France where a national survey based on a mathematical approach to 'trigonometric' surveying led the way.
He then plotted them along x and y axes that he changed periodically for the sake of methodological soundness and fit the graphs to standard parabolic and 'trigonometric' curves.
