### How do you Solv Trigonometry using Series for sine?

All two other basic ratios can be defined in terms of sine, as follows:cosine = sqrt(1 - sine2) and then tangent = sine/cosine. You need to know the quadrant of the angle to determine whether these ratios are positive or negative. The cosecant, secant and cotangent ratios are simply reciprocals and so easily derived from the above definitions. Read More

In advanced mathematics, familiar trigonometric ratios such as sine, cosine or tan are defined as infinite series. For example, sin(x) = x - x3/3! + x5/5! - ... Such series are used to calculate trig ratios and the proof of their their convergence to a specific value depends on calculus. Read More

### What is the meaning of trigonometry?

The word trigonometry comes from two Greek words, trigonon, meaning triangle, and metria, meaning measurement. This is the branch of mathematics that deals with the ratios between the sides of right triangles with reference to either of its acute angles and enables you to use this information to find unknown sides or angles of any triangle. Trigonometry is not just an intellectual exercise, but has uses in the fields of engineering, surveying, navigation, archicecture, and… Read More

### History's of trigonometry?

History of trigonometry. The history of trigonometry dates back to the early ages of Egypt and Babylon. Angles were then measured in degrees. History of trigonometry was then advanced by the Greek astronomer Hipparchus who compiled a trigonometry table that measured the length of the chord subtending the various angles in a circle of a fixed radius r. This was done in increasing degrees of 71. In the 5th century, Ptolemy took this further by… Read More

### What is the difference between plane trigonometry and spherical trigonometry?

Trigonometry is the study of plane and spherical triangles. Plane trigonometry deals with 2 Dimensional triangles like the ones you would draw on a piece of paper. But, spherical trigonometry deals with circles and 3 Dimensional triangles. Plane trigonometry uses different numbers and equations than spherical trigonometry. There's plane trigonometry, where you work with triangles on a flat surface, then there's spherical trigonometry, where you work with triangles on a sphere. Read More

### Who are the fathers of trigonometry?

There is no one or two or a few 'fathers of trigonometry.' Ancient Sumarians, Babalonians started using ratios of sides of triangles. The Greeks continued the study, but emphasized geometric methods instead of algebraic methods that used in trig. Egyptians, Persians, Arabic, and Indians all contributed to the development of trig. This whole process took about 2000 years, maybe more. Read More
