Pythagorean Triples
Almost everyone knows of the "3-4-5triangle," one of the right
triangles found in every draftsman's toolkit (along with the
45-45-90). This triangle is different from most right triangles
because it has three integer edges. Pythagoras' theorem tells us that
the squares of the sides of a right triangle sum to give to the square
of the hypotenuse:
32 + 42 = 52
I am often asked whether this relationship is unique, or if there are
other right triangles with three integer edges as well.
When we randomly select two integers and add their squares, we usually
acquire a non-integer square as a result; thus 32 + 52 = 34, or 42 + 72
= 65, and so on. Neither 34 nor 65 are integer squares. This type of
result seems to be the general go of things; so the question posed is
not without merit.
It turns out that there are an infinite number of right triangles with
integer edges, which is relatively simple to see.
Consider a right triangle with edges a, b, and c such that
a2 + b2 = c2
The terms a and b are the sides of the right triangle so that a and b the equation. Let's choose b2:
a2 = c2 - b2
Next, from basic algebra we see that we can factor the right-hand
side:
a2 = (c + b)(c - b)
Now let's assume that a, b, and c are integers. Then a2, (c + b), and
(c - b) must also be integers. Furthermore, since the product (c +
b)(c - b) is equal to an integer square, both (c + b), and (c - b)
must be integer squares. Let u and v be integers and set
c + b = 2u2
c - b = 2v2
where u2> v2. (Why do we place a 2 in front of u2 and v2? Keep
going-the reason should become clear shortly.
Problem Statment:You have to figure out how many total various sized squares are in an 8 by 8 checkerboard. You also have to see if there is a pattern to help find the number of different sized squares in any size checkerboard.Process: You have to figure out how many total different sized squares you can make with a 8x8 checkerboard. I say that there would be 204 possible different size squares in an 8x8 checkerboard. I got that as my answer because if you mutiply the number of small checker boards inside the 8x8 and add them together, you get 204. You would do this math because if you find all of the possible outcomes in the 8x8, you would have to find the outcome for a 7x7, 6x6, 5x5, 3x3, and 2x2 and add the products of

In 1665, the Binomial Theorem was born by the highly appraised Isaac Newton, who at the time was just a graduate from Cambridge University. He came up with the proof and extensions of the Binomial Theorem, which he included it into what he called “method of fluxions”. However, Newton was not the first one to formulate the expression (a + b)n, in Euclid II, 4, the first traces of the Binomial Theorem is found. “If a straight line be cut at random, the square on the whole is equal to the squares on the segments and twice the rectangle of the segments” (Euclid II, 4), thus in algebraic terms if taken into account that the segments are a and b:

The plural of focus is foci. The midpoint of the segment joining the foci is called the center of the ellipse. An ellipse has two axes of symmetry. The longer one is called the major axis, and the shorter one is called the minor axis. The two axes intersect at the center of the ellipseThe center of the ellipse is at (h, k). The radius of ellipses are not a constant distance from the center. To find the distance to the curve from the center you have to find the distance from the center to the curve for the x and y separately, these points are called vertices. The vertices are on the major axis and minor axis. The major axis is the longer axis and the minor axis is the shorter axis through the center of the ellipse. To find the distance from the center in the x direction you take the square root of a2. To find the distance from the center in the y direction you take the square root of b2. You then will have two points on the x direction and two points in the y direction and you use these four points to draw your ellipse. Ellipses are symmetrical across both of there

There is a triangle called the Heronian triangle. It has area and side lengths that are all integers. The Heronian triangle is named after the great hero of Alexandria. The term is sometimes applied more widely to triangles whose sides and area are all rational numbers. An Isosceles triangle is a triangle that has two sides of equal length. Sometimes is specified as having two and only two sides of equal length. Triangles are polygons with the least possible number of sides, which is
