# What does Greek word graph mean?

## What does Greek word graph mean?

There is much to say about the Greek root graph which means ‘to write,’ so let this ‘written’ discourse begin! One of the most common uses of this root is in the suffix -graphy. Geography is simply ‘writing’ about the physical characteristics of the Earth.

What is the origin of graph?

In mathematics, an origin is a starting point on a grid. It is the point (0,0), where the x-axis and y-axis intercept. The origin is used to determine the coordinates for every other point on the graph.

Where is the point of origin?

On the flat coordinate plane, there are two axes, the vertical y-axis and the horizontal x-axis. The origin is the point where they intersect. This point has the coordinates 0,0 and is usually labelled with the letter O.

### What is the origin of a straight line?

The equation of a straight line is y = mx + c. If c, which is the intercept, is = 0, this means that y = mx. This is the origin of that line. If the coordinates of a line are given as (x1, y1) = (4, 12) and (x2, y2) = (12, 34), this means that the line does not pass through the origin at any point all.

What is the origin of a function?

The starting point. On a number line it is 0. On a two-dimensional graph it is where the X axis and Y axis cross, such as on the graph here: Sometimes written as the letter O.

What is the origin of a shape?

Usually, you will be asked to rotate a shape around the origin, which is the point (0, 0) on a coordinate plane. You can rotate shapes 90, 180, or 270 degrees around the origin using three basic formulas.

#### What does Origin mean?

origin, source, inception, root mean the point at which something begins its course or existence. origin applies to the things or persons from which something is ultimately derived and often to the causes operating before the thing itself comes into being.

What are the 7 types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc.

Does God make straight lines?

“God does not build in straight lines.” That’s what the character played by Logan Marshall-Green (whom you may know as Trey Atwood from The O.C.) declares in Ridley Scott’s new sci-fi thriller Prometheus. In the scene, the questionably named spaceship Prometheus is about to land on an alien world.

## What is the most straight thing in the world?

From Google search: The sun is the most perfectly round natural object known in the universe, say scientists who have conducted precise measurements of its dimensions.

What shape does not exist in nature?

What is a shape? Mathematical shapes can exist in various dimensions. They can also be defined very specifically. A mathematical circle doesn’t exist in nature because a) it is a two dimensional object and b) shapes in nature are quantised – at some point a flower is made of cells and then atoms.

What is a perfect shape?

A two-dimensional equable shape (or perfect shape) is one whose area is numerically equal to its perimeter. For example, a right angled triangle with sides 5, 12 and 13 has area and perimeter both have a unitless numerical value of 30.

### Are circles perfect?

For a circle to be perfect, we would need to measure an infinite number of points around the circle’s circumference to know for sure. Each point would need to be precise from the particle level to the molecular level, whether the circle is stationary or in motion, which makes determining perfection a tricky feat.

Is the sun a perfect circle?

The sun is the most perfectly round natural object known in the universe, say scientists who have conducted precise measurements of its dimensions. As a spinning ball of gas, astronomers had always expected our nearest star to bulge slightly at its equator, making it very slightly flying-saucer shaped.

How are circles used in real life?

– One prime example of a circle that you can find in real life is a Ferris Wheel. All the points along the outer rim of the wheel are equidistant from the center. – Another good example of circles are bicycle wheels. Circles are the best shape for a bicycle because they roll very easily because they are round.

#### Why are circles important?

Circles are still symbolically important today -they are often used to symbolize harmony and unity. For instance, take a look at the Olympic symbol. It has five interlocking rings of different colours, which represent the five major continents of the world united together in a spirit of healthy competition.

Why is Circle important in our life what would the world be like without circles?

Life without circles would be as a square. All the planets including earth would not exist in a circular shape. There would be no movement of wheels of cars and bicycles on the road. Also scientific terms like rolling friction would not exist.

Why do we find circles so beautiful?

In other words, angular shapes tend to trigger fear and therefore aversion and dislike. As the ultimate curvilinear shape, the circle embodies all of the attributes that attract us: it is a safe, gentle, pleasant, graceful, dreamy, and even beautiful shape that evokes calmness, peacefulness, and relaxation.

## What is special about circles?

Properties. The circle is the shape with the largest area for a given length of perimeter (see Isoperimetric inequality). The circle is a highly symmetric shape: every line through the centre forms a line of reflection symmetry, and it has rotational symmetry around the centre for every angle.

Where do we see circles in everyday life?

Answer. Some examples of circles in real life are camera lenses, pizzas, tires, Ferris wheels, rings, steering wheels, cakes, pies, buttons and a satellite’s orbit around the Earth. Circles are simply closed curves equidistant from a fixed center.

Why are circles so strong?

The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.

### What do circles represent?

The circle is a universal symbol with extensive meaning. It represents the notions of totality, wholeness, original perfection, the Self, the infinite, eternity, timelessness, all cyclic movement, God (‘God is a circle whose centre is everywhere and whose circumference is nowhere’ (Hermes Trismegistus)).
