plane trigonometry

The classical plane trigonometry problem is to specify 3 of the 6 characteristics and to determine the three others.

The following year he attended military college to study arithmetic, algebra, speculative geometry and plane trigonometry.

In 1950-1951 the department expanded a little, offering 34 classes ranging from college algebra to analytic geometry to plane trigonometry.

Some time shortly after 1946 however the department developed thirty-four additional courses in everything from collegiate algebra to analytic geometry and plane trigonometry.

His book, De Driehouckhandel, included Plane Trigonometry.

The mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry, and spherical trigonometry.

Instead, the early Chinese used an empirical substitute known as chong cha, while practical use of plane trigonometry in using the sine, the tangent, and the secant were known.

During 1941, admission requirements were changed and applicants were required to have attained a college degree as well as one course in plane trigonometry and one additional year of mathematics.

He wrote a book named "PLANE TRIGONOMETRY" which is considered a masterpiece till date.

And this gives the answer to the first question; double algebra is nothing but analytical plane trigonometry, and this is why it has been found to be the natural analysis for alternating currents.

In spherical trigonometry, the law of cosines (also called the cosine rule for sides) is a theorem relating the sides and angles of spherical triangles, analogous to the ordinary law of cosines from plane trigonometry.

"THE FORMULAE OF PLANE TRIGONOMETRY," 1861 printed with symbols (instead of words) to express the "goniometrical ratios."
