What are rational numbers

In this blog let us see What are rational numbers:Any number which can be expressed in the form a/b is called as a rational number where a and b are non zero integers. Since b can be any integer, it can even be 1. So all the integers are rational numbers.Now let us see what is a whole number.The normal integer is called as whole number. It is refer the positive integer. Each whole number proceeds with all operations.Hope you like the above example of What are rational numbers.Please leave your comments, if you have any doubts.

What is Trigonometry

What is Trigonometry:Let us learn about what is Trigonometry,Trigonometry (from Greek trigōnon "triangle" + metron "measure") is a branch of mathematics that studies triangles, particularly right triangles.Trigonometry deals with relationships between the sides and the angles of triangles, and with trigonometric functions, which describe those relationships and angles in general, and the motion of waves such as sound and light waves.Once we understand the meaning of Trigonometry we can also learn about trigonometric equations.Hope you like the above example of What is Trigonometry.Please leave your comments, if you have any doubts.

Area of a Rectangle Formula

Area of a Rectangle Formula:Let us learn about the Area of a Rectangle Formula.Rectangle is a four sided plane surface area whose opposite sides are equal point and parallel point and every angle is a right angle. Area of the rectangle can be found by multiplied the base and height. Area of rectangle = length x breadth.To find the area of a region for enclosed plane figure, we have to draw a figure and write an appropriate formula. Then substitute the given values, and calculate the required area.Now we can understand the meaning of triangle rectangle.Rectangular is one type of polygon,whereas Triangle It has tree sides.The sum interior angle of equilateral triangle is 180 degree each angle is 60 degree.Hope you like the above example of Area of a Rectangle Formula.Please leave your comments, if you have any doubts.

Perpendicular bisector

In geometry, two lines or planes (or a line and a plane), are considered perpendicular (ororthogonal) to each other if they form congruent adjacent angles (a T-shape).

Perpendicular Definition: Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. It is possible to draw a perpendicular to a line without any measurement using just a compass and straightedge using techniques developed thousands of years ago by the Greeks.

In general, 'to bisect' something means to cut it into two equal parts. The 'bisector' is the thing doing the cutting. With a perpendicular bisector, the bisector always crosses the line segment at right angles (90°).We also use many calculators to solve many problems at times.One of these many calculators is hypotenuse calculator. Hope you like the above example of Perpendicular Bisector. Please leave your comments, if you have any doubts.

Formula for circumference of a circle

Formula for circumference of a circle:Let us learn the Formula for circumference of a circle, The formula to find the Circumference Cof a circle is

C=2*Pi*r

Which means Circumference of a circle is 2 times the value of pi times r

Where, r = radius of a circle and

Pi=3.142 which is a constant value.We can learn about the perimeter of a circle,in the blogs that we will publish in the future.Hope you like the above example of Formula for circumference of a circle.Please leave your comments, if you have any doubts.

6 sided shape

6 sided shape:One of the most common examples of a 6 sided shape is our very own "DICE".A die (plural dice, from Old French dé, from Latin datum "something given is a small polyhedral object, usually cubic, used for generating random numbers or other symbols. This makes dice suitable as gambling devices, especially for craps or sic bo, or for use in non-gambling tabletop games.A traditional die is a cube (often with corners slightly rounded), marked on each of its six faces with a different number of circular patches or pits called pips. us next learn about the 7 sided polygon,In geometry a polygon (pronounced /ˈpɒlɪɡɒn/) is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices or corners. An n-gon is a polygon with n sides. The interior of the polygon is sometimes called its body. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions.Hope you like the above example of 6 sided shape.Please leave your comments, if you have any doubts.

Area of the Quadrilateral

Area of the Quadrilateral: In quadrilateral the opposite sides are equal lengths; the opposite angles are equal; or that the diagonals bisect each other.In ABCD quadrilateral diagonal is a straight line joining two alter AC and DB are the diagonals.Areas of quadrilateral is measured in terms of square units such as square inches,squarefeet or square meters.Now let us look at area of a quadrilateral problems.area of a quadrilateral problems, Areas of quadrilaterals = √{(s-a)(s-b)(s-c)(s-d) -1/4(ac+bd+pq)(ac+bd-pq)}, where a,b,c and d are the four sides of the quadrilateral, p and q are diagonals, and s = (a+b+c+d)/2.Let us now calculate the area of a quadrilateral.


You can achieve the same result with this formula:

Areas of a quadrilateral Problem = √{(s-a)(s-b)(s-c)(s-d)-abcd(cos square theta)}

where theta = 1/2 (sum of two opposite angles)

Another method:

The area of quadrilateral ABCD = 1/2Area of ABD +1/2 area of BDC

= ½ x base x altitude + ½ x base x altitude

= 1/2d ( h1 + h2)

Hope you like the above example of Area of the Quadrilateral.Please leave your comments, if you have any doubts.

Least Common Multiple

Least Common Multiple:In arithmetic number of theory is the least common multiple or lowest common multiple (LCM) or smallest common multiple of two integers a and b is the smallest positive integer that is a multiple of both of a and of b. Since it was a multiple, it can be divided by a and b without a reminder. If either a or b is 0, so that number is no such positive integer, then LCM(a, b) is defined to be zero.Let us understand the L.C.M with an example.Example 1:Find lowest common multiple for the number 24 and 34.

On finding the LCM we have to find the prime factors for the given number.

24 : 2 2 2 3

34 : 2 17

---------------------------

LCM : 2 2 2 3 17

Lowest common multiple for the numbers 24 and 34 is 2 * 2 * 2 * 3 * 17 = 408.In this blog a simple explanation is given about math least common multiple-L.C.M.Hope you like the above example of Lower Common Multiple.Please leave your comments, if you have any doubts.

Distance formula

Distance formula:Find the distance between the following pair of points:

A (1,2) and B (4,5).
Suggested answer:

Using the distance formula,

The next important thing that we will learn is Distance Formula Math:
* The distance method can be obtained by generate a triangle and with the Pythagorean Theorem to locate the length of the hypotenuse.
* The hypotenuse of the triangle will be the distance connecting the double points.
* The subscripts refer to the original and next points; it doesn't material which points you call original or next.

Let us now see Formula of Distance :

Distance = [sqrt((y2-y1)^2 + (x2 -x1)^2))]

Here (x1, y1) and (x2, y2) are the end points of the line segment. We need to find the distance the two points.Hope you like the above example of Complex Numbers.Please leave your comments, if you have any doubts.
