Introduction to Ellipse

Let us study Ellipse formula,
An ellipse is the locus of a point which moves so that its distance from a fixed point is in a constant ratio, less than one, to its distance from a fixed line.
The fixed point is called the focus of the ellipse. The fixed line is called the directrix of the ellipse. The constant ratio is called the eccentricity of the ellipse and is denoted by e.
Equation of an Ellipse
Let S(h,k) and ax+by+c=0 be the focus and directrix of an elipse respectively. Let e be the eccentricity of the ellipse.
Let P(x,y) be a general point on the ellipse.

What is Graph Theory

Let us study What is Graph Theory,

Graph Theory:
In learn online representations, the graph theory is used. The selected area shows the isomerism’s common area between graphs and other forms. In spectral graph theory, the graphs can be denoted by algebraic structures.
Order Theory:
In learn online representations, the order theory is also used. From the experiments, each graph is shaped by the intersection of the graphs in an ordered set called as containment or inclusion relation. The containment instructions for a class of normal objects are Boolean pattern of dimensional order n.

Explain Solution set

Let us study about Solution set,

The set of ordered pairs (x,y), which satisfy the given inequation, is called the solution set of the inequations.
Graphical representation of linear inequations on the real number line

A real number line can be used to represent the solution set of an inequation (Linear).
The convention is that O (a hollow circle) marks the end of a range with a strict inequality (i.e. <>) and (a darkened circle) marks the end of a range involving equality as well as inequality.

What do you call a six sided shape

What do you call a 6 sided shape ?

Hexagon is one of the polygon type. In polygon different shapes contains different sides. Each of the polygon shape is named as different based on the shape and size. One of the six sided shape is the hexagon. Hence, the polygon contains the 6 sided and 6 vertices. Schlafli symbol present in the regular hexagon. The interior angle of any degree is 720 degree. Let we see about many information about hexagon.

Properties of Six Sided Shape Hexagon:

From the above definition we can define many properties.

Property 1: Amount of triangles used in hexagon

Property 2: Amount of diagonal used in the hexagon

Property 3: Total number of the internal angles used in the hexagon shape.

I hope the above explanation was useful.

Arc Length and Arc Length Formula

Arc Length and Arc Length Formula: Arc refers to a part of a circle or a curve. In case of the circle contains the minor arc and major arc. The arc length of minor is the multiplication of circumference of a circle and fraction of an angle (0/360).The length of an arc is called arc length. Radius of a circle and angle (o) can be making a formula of length.The arc length can be either small or large.Let us learn some key points of Arc Length Problems. The length of arc of the circle is given by the central angle divided by 360 degree which is multiplied by the circumference. If the circumference of the circle is given by 2pr then the length of arc of the semicircle is pr.


Let us now look at Arc Length Of Circle Theorem.The given axes be AB and CD .Take the region in Centre e and foci, mark points in any way as you like as shown in the figure.Describe arcs at g, g, g, and g then these points of intersection will be in the curve of the ellipsis upon f and f, with b 1 for radius.In similar way we will find other points. We can find h by taking 2 for one radius and b2 for another radius. By taking b 3 for one radius, and a 3 for the other i is found , always using the foci for centres. Trace the points c, g, h, i, b, etc.,Then we will be getting an ellipse shape as shown in the figure.Hope you like the above example of Arc Length and arc Length Formula.Please leave your comments, if you have any doubts.

Derivatives

Applications of Derivatives Help:Let us understand the concept of application of derivatives help.After having studied functions, limits and continuity in the previous chapter, we shall further divide the class of continuous functions into two sub classes, derivable and non-derivable.After having studied functions, limits and continuity in the previous chapter, we shall further divide the class of continuous functions into two sub classes, derivable and non-derivable.The derivative, measures the rate at which the dependent variable changes with respect to the independent variable.










It is one of the most important ideas in Calculus. The differentiation of functions are widely used in science, economics, medicine and computer science.While studying derivatives we are faced with many questions related to application of Derivatives.The degree of a differential equation whose differential coefficients have positive integral powers is defined as the highest power(positive integral index) of the highest order derivative in it.The last but not the least concept which needs attention is application of Derivatives solved probles.We can find many solved problems related to this topic.Hope you like the above example of Derivative.Please leave your comments, if you have any doubts.

Learn Sine Rule

Let us study about sine rule in Trigonometry,

Introduction :

An equation containing the trigonometrical functions of an unknown quantity is termed as a trigonometrical equation, which holds for some values (and not for all values) of the quantities involved.
Co-terminal Angles

The angles (2p + A), (4p + A)......have the same initial and terminal arm as the angle A and so these angles are called co-terminal angles. For all such angles, the value of any trigonometric ratio is the same. Thus, all co-terminal angles are trigonometrically equivalent.

Theorem 1
General solution of sin q = k.

Theorem 2
General solution of cos q = k.

Theorem 3
General solution of tan q = k.

Theorem 4
General solution of acosq + bsinq = c.

I hope the above explanation helped you, now let me explain Cos.

Introduction of coordinate Geometry

Let us learn about coordinate Geometry,

The use of geometry dates back to before the beginning of history. However, it was often used in a very practical manner. It wasn't till about 600 BC that mathematicians began using formal logic and reasoning.

Coordinate plane--a two-dimensional surface on which a coordinate system has been set up; invented by Rene Descartes; also called Cartesian plane, graph, coordinate grid

Coordinates--the numbers in an ordered pair that locate a point in the coordinate plane

Ordered pair--a pair of numbers, written as (x,y), that represents a point on a coordinate grid

Line segment--the part of a line between two points on the line, including the two points

X-axis--the horizontal number line on a coordinate grid

Y-axis--the vertical number line on a coordinate grid

Quadrants, Origin

To plot points, always write the x value first and then the y value.

Ex. (2, 3) (3, -1) (-2, 3) (-3, -2)

Postulates and Theorems

Let us study about postulates and theorems,

A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven. Listed below are six postulates and the theorems that can be proven from these postulates.

* Postulate 1: A line contains at least two points.

* Postulate 2: A plane contains at least three noncollinear points.

* Postulate 3: Through any two points, there is exactly one line.

* Postulate 4: Through any three noncollinear points, there is exactly one plane.

* Postulate 5: If two points lie in a plane, then the line joining them lies in that plane.

* Postulate 6: If two planes intersect, then their intersection is a line.

* Theorem 1: If two lines intersect, then they intersect in exactly one point.

* Theorem 2: If a point lies outside a line, then exactly one plane contains both the line and the point.

* Theorem 3: If two lines intersect, then exactly one plane contains both lines.

Comparing Statistical Results

Let us study how to do comparing statistical results,
Making predictions is only one use of statistics. Suppose you have recently developed a new headache/pain remedy that you call Ache-Away. Should you produce Ache-Away in quantity and make it available to the public? That would depend, among other concerns, upon whether Ache-Away is more effective than the old remedy. How can you determine that?

One way might be to administer both remedies to two separate groups of people, collect data on the results, and then statistically analyze that data to determine if Ache-Away is more effective than the old remedy. And what if the results of this test showed Ache-Away to be more effective? How certain can you be that this particular test administration is indicative of all tests of these two remedies? Perhaps the group taking the old remedy (the control group) and the group taking Ache-Away (the treatment group) were so dissimilar that the results were due not to the pain remedies but to the differences between the groups.

It's possible that the results of this test are far off the results that you would get if you tried the test several more times. You certainly do not want to foist a questionable drug upon an unsuspecting public based upon untypical test results. How certain can you be that you can put your faith in the results of your tests? You can see that the problems of comparing headache remedy results can produce headaches of their own.
Hope the above explanation was useful to you.
