Math History

Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

Which word defines the measurement of the distance around a figure?

The perimeter of a shape is the distance around it. The perimeter of a circle is called its circumference. Circumference can be calculated by 2 x pi x the circle's radius.

What does within which the circle was circumscribed mean?

There is a contradiction in the question.

A circumscribed circle is the smallest circle that will contain the shape in question. For example, the circumcircle (circumscribing circle) of a triangle is the smallest one which will contain the triangle. However, the question refers to "within which the circle" which would imply an inscribed circle. This is the biggest circle that can be wholly enclosed within the shape in question.

The two are obviously not the same and the question needs to be clear as to which one of the two is intended.

Hot to remove the negative numbers from a given set of numbers in excel?

It depends on what you mean by 'remove'. If you just want the numbers to appear there, but not able for anyone to see them, then you could create a conditional formula where any number that is negative would be the color white. If you wanted to Zero out any numbers that are negative, then you would make an if/then statement (conditional), like: =IFcell#(<=0,0,*) Which basically says that if cell # is less than or equal to 0, then that cell will show 0, if not, it will remain the positive number that it should be. Im not sure if this will help....I would need a little bit more of an explination of what you were trying to do. Hope it helps a little.

When was pi dicovered?

It was a Greek letter,and was first used in math in 1706 by William Jones.

How do you use measurement at home?

You use volume measurement to measure water and other liquids such as cooking or pouring a cup of water.

You measure the house temperature with a thermometer.

You measure weight (or mass) with a scale to weigh yourself or your food.

You measure velocity (and acceleration) while driving.

You measure distance, length or size with a ruler, or a meter stick or any other measurement tool.

What kind of angle is always the same distance apart?

An angle has no distance and so there is no angle which is the same distance apart.

What mathematical disaster does the derivative avoid?

The derivative was introduced to clarify the concept of "slope", specifically in the case of curves. It was not created specifically to avoid a "mathematical disaster", but it was possible to formalize the definition of slope (derivative) in such a way that concepts that are not very precise, such as "infinitely small", are avoided. This has been done by defining the derivative in terms of limits.

What are the numbers that have an odd factor?

Every integer number has an odd factor unless it doesn't, i.e. unless it only has even factors. An even factor can have an odd factor, unless it has only factors 2 (since it is the only even prime).

So, a number has an odd factor if it is unequal to a power of 2.

Note that 0 is not a power of 2 and has all odd factors . . .

What is the multiples of 9 8 4?

They are members of the infinite set of numbers of the form 72*k where k is an integer. Since the set is infinite, it is not possible to list them.

What is the contribution of Rene descartes?

Rene Descartes is regarded as the father of Western philosophy. His writings influence most of the subsequent writings in Western philosophy.

From what points in two cities is the distance between them measured?

Cities have GPS coordinates for their geographic centers. Distances are usually measured betweem them.
