Trigonometry made easy Teacherflix 18 Views • 2 years ago

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

Greek Mythology for Kids | What is mythology? Learn all about Greek mythology Teacherflix 18 Views • 2 years ago

What do you know about Zeus? Have you ever heard of satyr or centaur? In Greek Mythology for Kids, you will learn about many creatures and important gods and goddesses that the ancient Greeks created. Mythology is basically a way of telling stories. Native Americans, Egyptians, Romans, and many other cultures and religions have created myths. However, Ancient Greek mythology includes some of the most well-known stories.

Ancient Greece is the foundation for most western culture today. It lasted from 800 BC to 146 BC, which is when the Roman conquered Greece. The stories the Greeks developed are very popular, and they helped them explain the world around them. Because they didn't have access to the same level of science and technology that we do today, they couldn't explain natural phenomena like the sun rising and falling every day or the occasional thunderstorm.

To explain thunderstorms, for instance, the Greeks believed there was a god called Zeus that could control thunder and throw lightning bolts down from the sky. All the gods and goddesses had wildly exaggerated personalities and one or more magical powers. They were not considered good or bad. They used their powers for good, trickery, and adventure. Some gods were Titans, some were Olympians, and some were relatives of both.

Apart from the gods and goddesses, the ancient Greeks also came up with other interesting creatures and monsters. Cyclops, for example, was a monster with one eye. A centaur was a creature that was half horse and half man. Similarly, a satyr was half man and half goat. One of the most famous monsters was the gorgon called Medusa. Instead of hair on her head, she had snakes. The myth states that if someone looked directly into her eyes, they would immediately turn into stone.

Bacteria and Viruses for Kids | Learn about these two kinds of microorganisms Teacherflix 18 Views • 2 years ago

What is the difference between bacteria and viruses? In Bacteria and Viruses for Kids, you will learn all about these two microorganisms. The first thing you will learn is that not all bacteria are bad. In fact, the majority of bacteria on the planet and in your body are actually good. You can find bacteria in things like yogurt, soy sauce, and pickles!

So what are bacteria? They are single-celled organisms so small that you can't see them without a microscope. They don't have a nucleus like other single-celled Common shapes include rods, spirals, and spheres. All these organisms move in different ways too. Some move like swimmers using tail-like structures called flagella. Others stay still and don't move much at all. Then there are some that slither or slide their way around.

Most bacteria are not harmful. However, there are some that can make you sick. These are called pathogens. Common pathogens include food poisoning, leprosy, and typhoid fever. To fight these pathogens, you can use antibiotics or antiseptics. You can actually find antiseptics in soaps because it's how you keep your hands clean. Good bacteria, on the other hand, are good for many reasons. They help you digest food and keep your immune system strong. They also break down dead plant and animal material to help keep soil healthy. And, they produce about half of the oxygen in the atmosphere!

What about viruses? All viruses are bad. Scientists debate whether these organisms are living or dead because they don't have an organized cell structure and can't reproduce unless they attach themselves to a living cell. The word virus comes from the Latin word for "slimy liquid." These organisms attack healthy cells. As those cells reproduce, the virus reproduces too and spreads. Many kinds can pass from person to person through hand-shaking, food contact, and through water.

We hope you and your student(s) enjoyed learning about bacteria and viruses! If you want to learn even more, head over to our website and download one of our many free lesson plans about germs, full of activities, worksheets, and more!

Dinosaur Facts for Kids | Dinosaurs | Learn cool facts about the Age of Reptiles Teacherflix 18 Views • 2 years ago

What do you know about dinosaurs? In Dinosaur Facts for Kids, you will learn cool facts about many of these ancient animals. They lived during the Mesozoic era millions of years ago, which is divided into three smaller periods: Triassic, Jurassic, and Cretaceous. To this day, scientists still debate about the cause of their extinction. Was it because lots of volcanoes erupted at the same time? Or was it because a meteor crashed into Earth and caused a ton of damage?

Regardless, we can learn a lot about dinosaurs by studying their fossils. The first dinosaur bones ever found were found in China. The people originally thought they were the bones of giant dragons! The word dinosaur means “terrible lizard,” which works because most dinosaurs are classified as reptiles. Because of the work of paleontologists, we know that some dinosaurs walked on two legs while other walked on four. We also know that these terrible lizards varied greatly in size. Some were as small as chickens while others were bigger than a school bus!

The types of food that dinosaurs ate varied as well. Dinosaurs were either herbivores, carnivores, or omnivores, just like the animals of today. There are also some dinosaurs that are considered the ancient ancestors of birds!

We hope you and your student(s) enjoyed learning about these four different dinosaurs! If you want to learn even more, head over to our website and download one of our many free lesson plans about dinosaurs, full of activities, worksheets, and more!
