Who was the first person that created mathematics ?
iren [92.7K]

Mathematics encompasses many different types of studies, so its discovery can’t even be attributed to one person. Instead, mathematics developed slowly over thousands of years with the help of thousands of people!

How did it get started? No one can know for sure, but we can use our imaginations to think about how mathematicsmight have gotten its start. For example, if we go all the way back to prehistoric man gathering berries to eat, we can imagine how this basic task probably gave rise for a need for math. If you and your prehistoric buddy gathered a basket full of berries, you’d probably agree to split them evenly. First, you’d need to know how many berries you gathered. That means you’d need to count them. You might first need to come up with names for the basic units ofmeasurement. Is this how counting and the first numbers came about? No one knows, but you can see how this might be how it happened.

Similarly, division might have been born from the need to split that pile of berries evenly. How advanced didprehistoric man get with mathematics? Probably not far at all, but a need for certain mathematic principles likely arose from daily life and, as such, were discovered or created out of need rather than invented. Early learning eventually led to more advanced fields of mathematics, such as algebra, geometry, calculus, and trigonometry!

Because many mathematical discoveries were made as a result of necessity, it comes as no surprise that scientists believe that many basic mathematical functions, such as addition, multiplication, and the like, appeared thousands of years ago in various areas at the same time, including China, India, Mesopotamia, and Egypt.

The oldest clay tablets with mathematics date back over 4,000 years ago in Mesopotamia. The oldest written texts onmathematics are Egyptian papyruses. Since these are some of the oldest societies on Earth, it makes sense that they would have been the first to discover the basics ofmathematics.

More advanced mathematics can be traced to ancient Greece over 2,500 years ago. Ancient mathematician Pythagoras had questions about the sides of a right triangle. His questioning, research, and testing led to a basic understanding of triangles we still study today, known as the <span>Pythagorean </span>Theorem.

Most experts agree that it was around this time (2,500 years ago) in ancient Greece that mathematics first became an organized science. Since that time, mathematical discoveries have spurred other mathematicians and scientists to build upon the work of others, constantly expanding our understanding ofmathematics and its relation to the world around us.

Hope this helps! :)

solution: x+5= -x-5

x= -5

1. Subtract 5 from both sides

2. Simplify

3. Add x from both sides

4. Simplify

5. Divide both sides by two

Someone please explain to me how to get the answers to these 3 problems. (also ignored the darken circles since they are incorre
Delvig [45]

Answer:

  4.  y is the angle between -π/2 and π/2, inclusive, whose sine equals x

  5.  QI and QII

  6.  QI and QIV

Step-by-step explanation:

4. Just as an exponent of -1 indicates the inverse (reciprocal) of a variable ...

  x^{-1}=\dfrac{1}{x}

so an "exponent" of -1 on a function name indicates the inverse of the function. (The same notation is used to indicate the inverse of other things, as well.) That is, the notation ...

  y=\sin^{-1}{(x)}

indicates the inverse of the sine function, also called the <em>arcsine</em> function. The above notation can be read as "y equals the angle whose sine is x".

In other words, the sine function takes an angle as an argument and gives a pure number. The arcsine function takes a pure number as an argument and gives an angle.

(Unless otherwise specified, the default measure for angles is radians. Most calculators can be set to use angles in degrees or in radians. You need to be sure which mode you have set.)

_____

<em>Comment on the graph</em>

The attached graph shows one full cycle of sine, cosine, and tangent functions. Each function has a portion highlighted by dots. The highlighted portion corresponds to the portion for which the inverse function is defined. This is a portion of the curve that passes the horizontal line test, so the result of the inverse function is single-valued as a <em>function</em> result must be.

I have also identified the angle quadrants as Q3, Q4, Q1, Q2. By comparing the dotted function sections to the quadrant identifiers, you can see the answers to problems 5 and 6.

The image of where the various inverse trig functions are defined is a good one to keep in your head whenever you're working with those functions.

_____

5. The arccos function is defined in quadrants I and II.

6. The arctan function is defined in quadrants IV and I.
