Archaeologists identify different tools used by the civilization, using trigonometry can help them in these excavates. They can also use it to measure the distance from underground water systems Trigonometry was initially used in astronomy. Before the sixteenth century, the subject of astronomy was based completely on the concept that Earth is placed in the center of a number of nested spheres. Therefore, it can be said that trigonometry was mainly used for calculating the positions of planets and stars Trigonometry (from Greek trigōnon, triangle and metron, measure) is a branch of mathematics that studies relationships between side lengths and angles of triangles.The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest.

- An art teacher is a college-trained educator with state certification to teach an appreciation for the forms, creation, and importance of art in history and culture. The steps to become an art teacher in any state are relatively similar Marine biologists use trigonometry and algebra to establish measurements. They also use math for measurement equivalents, as they frequently need to convert between standard and metric units of measurement. Because math is the essential language of science, marine biologists use math to solve a number of complex problems in their line of work What does geometry have to do with anything? 1. In order to plan and build accurately, you must have a great knowledge of angles. For Example: This is a classroom. All the angles must be 90 degrees for the walls to properly support the ceiling. If these walls were 110 degrees, the ceiling would collapse of the people inside. 90 90 Simply put, geometry is a branch of mathematics that studies the size, shape, and position of 2-dimensional shapes and 3-dimensional figures. Although ancient Greek mathematician Euclid is typically considered the Father of Geometry, the study of geometry arose independently in a number of early cultures. Geometry is a word derived from Greek The solution to this is found with the quadratic formula: So our formula for the golden ratio above (B 2 - B 1 - B 0 = 0) can be expressed as this: 1a 2 - 1b 1 - 1c = 0. The solution to this equation using the quadratic formula is (1 plus or minus the square root of 5) divided by 2: ( 1 + √5 ) / 2 = 1.6180339 = Φ So, we use sin(n*x) to get a sine wave cycling as fast as we need. Often, the phrase sine wave is referencing the general shape and not a specific speed. Part 2: Understanding the definitions of sine. That's a brainful -- take a break if you need it. Hopefully, sine is emerging as its own pattern
