How is trigonometry used in daily life?

Answer 1

Applications of trigonometry
Marine sextants like this are used to measure the angle of the sun or stars with respect to the horizon. Using trigonometry and an accurate clock, the position of the ship can then be determined from several such measurements.

There are an enormous number of applications 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 satellite navigation systems. The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.

Fields which make use of trigonometry or trigonometric functions include astronomy (especially, for locating the apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medical imaging (CAT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical sciences, land surveying and geodesy, architecture, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.

Answer 2

I am a millwright and I use trigonometry to calculate tapers when machining parts. We also use it to figure out grades and heights with a transit. For instance in school I had to give the teacher a measurement of height of a water tower plus or minus 1 foot using this method. I myself don't have everything memorized but I know where to find the information and how to apply it. You would probably be quite surprised how many things you learn that you think are irrelevant and then later realize their importance. Good luck!!!

Answer 3

when your playing baseball and get a triple, you know your are 3/4 of the way home. well, really that calculus.
