Mathematicians
Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

What value of x would the quotient (3x2 4x-5) Divided BY (x 2) not make sense?
If that denominator is x + 2, a value of -2 for x would not make sense as division by zero is undefined.
Are you sure you wrote this question correctly? You have already told us that the answer is 87:100.
Or do you men the ratio of men to women? If this is what you want, you have to divide 87 into 100 and you get 1:15 approximately, or 115:100.
Which concept can be used to prove that the diagonals of a parallelogram bisect each other?
Congruent triangles:
Take a parallelogram PQRS.
Draw in the diagonals PR and QS.
Let the point where the diagonals meet be M,
Consider one pair of the parallel sides, PS and QR, say.
Consider angles PSQ and RQS:
As PS and QR are parallel they are equal (Z- or alternate angles).
Now consider angles SPR and QRP:
As PS and QR are parallel they are equal (z- or alternate angles).
As PS and QR are opposite sides of a parallelogram they are equal in length; thus the triangles PMS and RMQ are congruent (Angle-Angle-Side).
As the two triangle are congruent, equivalent sides are equal in length.
Thus QM is the same length as MS and PM is the same length as MR
As QM is the same length as MS and QMS lie on a straight line, M must be the mid point of QS, ie the diagonal PQ bisects the diagonal QS
Similarly PM is the same length as MR and PMR lie on a straight line, thus M must be the mid point of PR, ie the diagonal QS bisects the diagonal PR
Therefore the diagonals of a parallelogram bisect each other.
Is there any case where the quotient of two integers wouldn't have a decimal answer?
Try these: 1/7, 2/7, 3/7. 4/7. 5/7. and 6/7. All are infinitely repeating numbers and thus cannot be written as simple decimals. These are not the only ones.
Pythagoras.
When did Alan turing invented enigma machine?
Alan Turing didn't invent Enigma you complete inbacile. He cracked the code that the Germans were sending with the Enigma machine once. And it wasn't just his it was a whole team of people.
What was Abraham de Moivre's contribution to the field of mathematics?
Abraham de Moivre was a French Mathematician (1667-1754).He was a protestant and came to London.His contribution to mathematics was in the mathematical branch in Statistics and derived (De Moivre's theorm)- the poisson distribution and hypergeometrical distributions on statistics,the derivation of probability density function of the normal distribution distribution in statistical analysis.
Why is Fibonacci considered one of the most talented mathematicians for the Middle Ages?
Fibonacci was one of the most important mathematicians of the Middle Ages. He was the person who first realized the implications of the Arabic numeral system and promoted it with his publication of Liber Abaci, which described it. If you want to understand the implications, try figuring out what you get when you divide CXXIV by XXXI, entirely in Roman numerals, then understand that was the only system medieval merchants had available until Fibonacci's book appeared.
Fibonacci also did a fair amount of original work in mathematics, publishing a number of books. There is a link to an article on him below.
What were some important events in Fibonacci's life?
Fibonacci was born in 1170 and died in the 1240's he now has a memorial next to the Leaning Tower of Pisa
Where are the 4 quadriants in a grid?
Quadrant I (x, y)
Quadrant II (-x, y)
Quadrant III (-x, -y)
Quadrant IV (x, -y)
Where x and y are both positive numbers.
How do we use Archimedes' discoveries today?
People all around America still use Archimedes discoveries today. Like The snail screw we use that to raise and move water. Another discovery from Archimedes we use today is pi. We use pi to find the circumference for circles. Everyone should use the "Principles of Archimedes" because we use that to weigh objects.
How is a cube the same as a pyramid?
the base consists of four sides and they are both 3 dimensional objects.
NO! Of course he didn't make pi. Pi is a constant that describes the ratio between the circumference and diameter of a circle. So he can not have made pi as it is a constant. Also, he didn't discover pi either, the earliest use of this constant is by the egyptians upon building the great pyramid at Giza in which 2*pi was used as the ratio between the height and perimeter of the pyramid.
So basically, no.
What made Leonardo Fibonacci famous?
What made him famous was the fact that he discovered the Fibonacci Spiral which appears almost everywhere in nature
Why was nicolaus Copernicus' theory so important?
because the people would never know and this history about planet would never exist
What did Archimedes contribute to the world of math?
He developed one of the earliest concepts of limits , a fundamental topic in calculus,. He used the limiting process along with his method of exhaustion to provide a very close approximation of pi.
He also developed a method of calculating volume through water displacement.
I am pretty sure that the public disagreed with him when he suggested that the Earth spun on its own axis every 24 hours because the public thought that if it spun that fast everything will blow away with the force of the extreme wind but that didn't happen obviously cause they didn't know about atmosphere.
I am pretty sure this question is right so don't have a go at me if it isn't, but you should check other websites and I think it's right cause in school we are doing and whole topic about the Heliocentric System which Copernicus came up with.
Hope it helped.
What is the laplace transform of log function?
The Laplace transform is a widely used integral transform in mathematics with many applications in physics and engineering. It is a linear operator of a function f(t) with a real argument t (t ≥ 0) that transforms f(t) to a function F(s) with complex argument s, given by the integral F(s) = \int_0^\infty f(t) e^{-st}\,dt.
