- 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.
- Indians also added to our knowledge of even more complicated branches of mathematics such as trigonometry and calculus.
- 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.

- Most of his papers are solutions to problems posed by Euler on spherical geometry, trigonometry, series, differential geometry and differential equations.
- Lexell made major contributions to spherical geometry and trigonometry.
- Moore wrote the sections on arithmetic, geometry, trigonometry and cosmography while the sections on algebra, Euclid and navigation were written by Perkins.
- My math class, trigonometry, will probably be the hardest one.
- If you were a surveyor, you could measure angles and then use high-school trigonometry to calculate distances.
- He would have an easier time teaching them trigonometry than the triangle.
- Cavalieri also wrote on conic sections, trigonometry, optics, astronomy, and astrology.
- He graduated in 1860 with an outstanding report, which mentioned in particular his exceptional skills in mathematics, in particular trigonometry.

Example sentencesExamples - Vallée Poussin also worked on approximation to functions by algebraic and trigonometric polynomials from 1908 to 1918.

adjective ˌtrɪɡənəˈmɛtrɪk(ə)lˌtrɪɡ(ə)nəˈmɛtrək(ə)l Rather than using geometrical methods, as Ptolemy had done, al-Battani used trigonometrical methods which were an important advance. Example sentencesExamples - Astronomy, time-keeping and geography provided other motivations for geometrical and trigonometrical research.
