The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.]]> 2018-11-11 15:34:11 UTC https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302993543 clil4ach https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302994756 There is an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellites navigation systems. The sine and cosine functions are fundamental to the theory of periodic functions, such as those that describe sound and lightwaves.]]> 2018-11-11 15:42:14 UTC https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302994756 clil4ach https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302996674 Other applications is: astronomy (especially for locating apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, audio synthesis, acoustic, optics, electronics, biology, medical imaging (CT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical science, land surveying and geodesy, architecture, image compressions, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.]]> 2018-11-11 15:54:53 UTC https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302996674 clil4ach https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302997733 In astronomy, trigonometry is often used to find distances to nearby stars and other celestial objects using a method of parallax. Parallax can be defined as the apparent shift of a nearby star against the fixed background that can be noticed as the Earth orbits the sun.]]> 2018-11-11 16:02:52 UTC https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302997733 clil4ach https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302998825 In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equationrelating the lengths of the sides of a triangle(any shape) to the sines of its angles. According to the law,
where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the opposite angles (see the figure to the right), while d is the diameter of the triangle's circumciercle.]]> 2018-11-11 16:10:41 UTC https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/302998825 clil4ach https://padlet.com/clil4ach/scholasticworkontrigonometry/wish/303000919 Given: side a = 20, side c = 24, and angle C = 40°. Angle A is desired.
