Exempel på hur man kan använda TRIGONOMETRY i en mening

• He is considered the founder of trigonometry, but is most famous for his incidental discovery of the precession of the equinoxes.
• A slide rule is a hand-operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry.
• Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law.
• In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
• The legacy of sexagesimal still survives to this day, in the form of degrees (360° in a circle or 60° in an angle of an equilateral triangle), arcminutes, and arcseconds in trigonometry and the measurement of time, although both of these systems are actually mixed radix.
• Long studied for its practical applications to astronomy, navigation, and geodesy, spherical geometry and the metrical tools of spherical trigonometry are in many respects analogous to Euclidean plane geometry and trigonometry, but also have some important differences.
• There are many ways to prove Heron's formula, for example using trigonometry as below, or the incenter and one excircle of the triangle, or as a special case of De Gua's theorem (for the particular case of acute triangles), or as a special case of Brahmagupta's formula (for the case of a degenerate cyclic quadrilateral).
• It is a necessary step for navigational calculations (derived from trigonometry) and for use with Global Positioning System (GPS) receivers.
• In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points.
• The word "Hipparcos" is an acronym for HIgh Precision PARallax COllecting Satellite and also a reference to the ancient Greek astronomer Hipparchus of Nicaea, who is noted for applications of trigonometry to astronomy and his discovery of the precession of the equinoxes.
• To a non-specialist, he would have seemed deeply knowledgeable in science and mathematics, but a close inspection of his essay and curriculum revealed that the extent of his mathematical teachings was limited to algebra, trigonometry and logarithms.
• The Pythagorean theorem, and hence this length, can also be derived from the law of cosines in trigonometry.
• Her father encouraged her to plunge ahead, and bought her three books for her self-study that summer: trigonometry, algebra, and geometry.
• The spherical trigonometry required for the latter endeavor is really quite basic, and the calculations tedious rather than difficult.
• Gustave Flaubert wrote this nonsensical problem, now known as the Age of the captain:

  Since you are now studying geometry and trigonometry, I will give you a problem.

• A good deal of it is astronomy, but it also contains key chapters on mathematics, including algebra, geometry, trigonometry and algorithmics, which are believed to contain new insights due to Brahmagupta himself.
• The Beulah Hill ridge was used as a sighting-point for the Anglo-French Survey (1784–1790), which measured the precise distance between the Royal Greenwich Observatory and the Paris Observatory, using trigonometry.
• Achievements that advanced Islamic and Western science came from al-Andalus, including major advances in trigonometry (Jabir ibn Aflah), astronomy (Al-Zarqali), surgery (Al-Zahrawi), pharmacology (Ibn Zuhr), and agronomy (Ibn Bassal and Abū l-Khayr al-Ishbīlī).
• This half-heartedness has never been completely overcome, and sexagesimal fractions still form the basis of our trigonometry, astronomy and measurement of time.
• For example, Paul von Hindenburg thought that the history of ancient battles should be minimized to give more time to modern, and that trigonometry was only useful to those who would be surveyors.
