Transcript of trignometry
What is Trigonometry?
Trigonometry is one of the many branches of mathematics. It studies triangles and the relationships between their sides, their angles, and other terms.
Some of the main things that are taught in trigonometry are the trigonometric ratios: sine, cosine, and tangent.
By the 10th century, Muslim mathematicians had developed and applied the theory of trigonometric functions -- sine, cosine, and tangent -- as well as spherical trigonometry.
Finding the height of a Mountain
To solve this problem, we
first measured the distance between the wall and a point on the sidewalk. This was 192 inches.
We found out Hibaa's height and then measured how high her line of sight is. This was 57 inches. Then we used the protractor to measure the angle of elevation from her eyes to the top of the masjid wall while she stood 192 inches from the wall. The angle was 69 degrees.
By using Trigonometry, we were able to find the height of the masjid wall, which was 500.2 inches
Finding the angle of depression looking down from the top of a high building.
After subtracting 69 and 90 from 180, the third angle is 21 degrees. Then we used the Law of Sines to find the height of the building and then added Hibaa's line of sight height to it.
Trigonometry is used many fields like astronomy, navigation, music theory, biology, chemistry, meteorology, oceanography, architecture, many different areas of engineering, and computer graphics.
