Question

Who published the trigonometry in 1595?
A) William Rowan Hamilton
B) Hipparchus
C) Bartholomaeus Pitiscus
D) Newton

Answer 1

Hint: Trigonometry is the study related to sides if a triangle.

Complete step by step solution: Option c is the correct answer.
In 1595, Pitiscus published a comprehensive trigonometry text, Trigonometria: sive de solutione tractus brevis et perspicius. This was the first time the word “trigonometry” was used to describe the study of the properties of triangles.


Note: Trigonometric ratios are the ratios between edges of a right triangle.
There are three basic trigonometric ratios:
1.Sine (sin) \[\sin A = \dfrac{{opposite}}{{hypotenuse}} = \dfrac{a}{c}\]
2.Cosine (cos) \[\cos A = \dfrac{{adjecent}}{{hypotenuse}} = \dfrac{b}{c}\]
3.Tangent (tan) \[\tan A = \dfrac{{opposite}}{{adjecent}} = \dfrac{a}{b}\]

Additional information:

1) Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles.
2) Trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics and navigation.
3) Driven by the demands of navigation and the growing need for accurate maps of large geographic areas, trigonometry grew into a major branch of mathematics.
4) Other fields that use trigonometry or trigonometric functions include music theory, audio synthesis, architecture, electronics, biology, CT scans and ultrasound) chemistry, seismology, meteorology, oceanography, image compression, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.
