0 a type of mathematics that deals with the relationship between the angles and sides of triangles, used in measuring the height of buildings, mountains, etc. -- （數學中的）三角學
I took the many courses offered: advanced algebra, solid geometry, and (boring, surveyorlike) trigonometry.
Most astronomical experts at that time admitted that some of the imported mathematical tools - such as trigonometry, logarithms, and astronomical tables - were useful.
Along with the geometrical model came new astronomical tables, instruments, and calculation tools such as trigonometry.
The scheme relied upon trigonometry and mathematics to compute longitude using heavenly bodies.
The mathematics assessment includes items that increase in difficulty from simple recognition of numerals to advanced concepts such as geometry and trigonometry.
These included works on chemistry, ship technology, geography, traditional mathematics, mining, and trigonometry.
Their automatically calculated trigonometry, the distance between the eyes and the two visual angles, offers a sensation of depth.
We have overloaded the arithmetic operators, trigonometry functions, and a few dozen other functions, to operate on expressions.
