Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. In this video we look at the use of trigonometry with right triangles, solving for both sides and angles.

BTW for those interested - the history of trigonometry history is fascinating!
The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
The use of trigonometry really took off due to it's use in navigation - trigonometry has been used for locating latitudes and longitudes of sailing vessels, plotting courses, and calculating distances during navigation.
Trigonometry is still used in navigation through such means as the Global Positioning System and artificial intelligence for autonomous vehicles.

But the truly cool trigonomic endevour was The Great Trigonomical Survey.
The Great Trigonometrical Survey was a project which aimed to measure the entire Indian subcontinent with scientific precision. It was begun in 1802 and completed of it in 1871.
Among the many accomplishments of the survey was measurement of the height of the Himalayan giants: Everest, K2, and Kanchenjunga. The Survey had an enormous scientific impact as well, being responsible for one of the first accurate measurements of a section of an arc of longitude.
Triangulation surveys were based on a few carefully measured baselines and a series of angles. The initial baseline was measured with great care, since the accuracy of the subsequent survey was critically dependent upon it. Various corrections were applied, principally temperature. An especially accurate folding chain was used, laid on horizontal tables, all shaded from the sun and with a constant tension. The early surveys made use of large and bulky theodolites made by William Carey, a Zenith sector made by Jesse Ramsden and 100-foot (30 m) chains!
Interesting aside - Everest was one of the leaders of the survey - and his name was pronounced Eve-rest not Ever-est! To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

In which John Green teaches you about the American Revolution and the American Revolutionary War, which it turns out were two different things. John goes over the issues and events that precipitated rebellion in Britain's American colonies, and he also explores the ideas that laid the groundwork for the new American democracy. Find out how the tax bill from the Seven Years' War fomented an uprising, how the Enlightenment influenced the Founding Fathers, and who were the winners and losers in this conflict. (hint: many of the people living in the Colonies ended up losers) The Revolution purportedly brought freedom and equality to the Thirteen Colonies, but they weren't equally distributed. Also, you'll learn about America's love affair with commemorative ceramics and what happens when rich white guys take the reins from rich white guys and put together a society of, by, and for rich white guys.

Educational video for children in which children will learn the /m/ sound in English. Little ones will discover how to pronounce the sound of the letter M through a fun song and numerous examples alongside our favorite seal, Feli. Phonics is a very successful method used to teach reading through letter sounds. In this simple video for children who are beginning to read, we work on phonemic awareness and phonological awareness, two important skills for early readers and young children who are developing reading skills. It is an interactive video that asks viewers to participate by singing and repeating the sounds along with Feli.

This video is a very useful and interesting resource for children to learn the sounds of the English language. It is an excellent video for preschool, primary, and bilingual education.

The near-term acceleration of the rate of temperature change shows an urgent need for research on the impacts of these changes for the environment and the human-built world. So, do we really need to grow into space? How can we do it in a sustainable way? It is high time for an integrated discussion of space matter with planetary concerns.

Our new comic series 'Space Rocks' will address these concerns adapted from the latest research articles. Stay tuned for more information.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Cosmology & Astronomy on Khan Academy: The Earth is huge, but it is tiny compared to the Sun (which is super huge). But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness!
