Trigonometry Functions

Spherical

This is trigonometry.

This is trigonometry.

We'll, here's our spherical earth. Well, it's supposed to be spherical.

Spherical light after explosion

Euclidean space, and spherical space.

The Trig part of Trigonometry literally means

I had just taken trigonometry in high school,

The child drew a spherical triangle.

This also points toward a spherical earth.

And that's how the spherical shape is created.

In this video I wanna give you the basics of Trigonometry.

This is exactly spherical, the same as the Earth.

I have a straight line on my spherical surface.

I'll provide you the basic trigonometry function for generating the polygons points.

It's more of a spherical cloud, and we think it exists.

Now with that out of the way let's learn a little bit of Trigonometry.

But there is another possibility that you all know of spherical space.

Today we don't need one million light bulbs to create a spherical display.

The toy model that's often used is called the spherical top hat model.

But two of these points really seem to point towards a spherical earth.

But I never really got logarithms, or I never really got trigonometry, or ratios...ratios killed me

The core functions of trigonometry, we're going to learn a little more about what these functions mean.

An important thing to remember is that, as shown throug h spherical top hat model.

In fact, everyone who was educated understood that the world was spherical since Aristotle's time.

The sum of the angles of a triangle on a spherical plane is more than 180 degrees.

I was thinking about mass produced spherical television sets that could be linked to orbiting camera satellites.

But for most of the rest, you see flattening of the distribution which normally should be spherical.

This clearly points towards a spherical earth, because on a flat disk shaped earth, this wouldn't happen.

I should tell you the idea that Christopher Columbus discovered that the world is spherical is total bull.

The ancient Greeks knew the earth was spherical, or at least they had good reason to believe it was.

This is the reason why the magnetic fields entangle, they link up to each other, so they make a spherical shape.

Now, if we want to distinguish between a spherical earth and a disk shaped earth, we have to use our evidence.

And instead of Fourier components, we are talking about spherical harmonics and any signal on the surface of the sphere can be expressed as a sum of spherical harmonics weighted properly component by component and formulas for each one of those exist and can be it computed.

At the same time, we have developed half spherical reactors, because we find these much... easier to manage for the space technology.

And this cloud of matter is much more spherical than the galaxy themselves, and it extends over a much wider range than the galaxy.

Let's start thinking about geometry by cataloging some of the evidence the Greeks had available to them and deciding which pointed towards a spherical earth.

From the data we had or from the data the Greeks had, some of it doesn't support either claim the spherical or the disk hypothesis.

The way we quantify this is through spherical harmonics, which is essentially in equivalent of Fourier decomposition on a sphere, schematically this is how it works.

Finally, the third axis turns around and the, that's really cluster collapses along that. and it will become, again, a quasi spherical object in the end.

And as I looked at it, it kind of tucked its arms under it, raised into a spherical shape and turned chocolate brown with two white stripes.

If you to take a box or a spherical clock hand from their previous exercisers and position it and rotate it, you'll get it something like this.

What we have realized is that...as you see there's an other reactor... most of the... objects in the Universe are... literally, circular, spherical, as you see.

Still, a man named Eratosthenes was able to answer this question using nothing more than some basic assumptions about the earth and the sun along with an understanding of geometry, trigonometry and shadows.
