Introduction of circular functions:
Trigonometric functions or Circular functions the functions of an angle in a triangle. These are very helpful in the analysis of the properties of triangles and used to describe the relationship between the angles and side lengths of triangles.
Sine, cosine, tangent are the most popular circular functions co-secant, secant and cotangent are their respective reciprocals.
Need help with solving right triangles
On the basis of an angle in a triangle, the sine function gives the y-component of a triangle and cosine function gives the x-component. The tangent function gives the slope of a triangle.

Right Triangles for Circular Functions

If one of its angle is right angle or equal to 90 degree. The hypotenuse and the other two sides being leg₁ and leg_{2which is} opposite to the right angle ,in the Right triangle only then the triangle is said to be a right triangle .Also, find interesting topic on Solving math with formula

Introduction of line graph pictures:

A pictures of graphs is one of the line charts. It is very easy to understand the data’s. We can compare two variables in line graph pictures. On Line graph pictures has each variable is plotting along each axis. A graph picture has a vertical and horizontal axis. Let we learn about line graph pictures.

Following statements are necessary for line graph pictures:
examples of line graphs.

• A line graph picture is a visually used to determine up to the frequency of incidence of different character of data.
• Give a summary of the data at top on line graph pictures (Title).
• Axes are known by what information is presenting on the each axes. It is representing data groups.
• They are best one to displaying information (values of data) and easy to make graph pictures.

Basic needs for graph pictures:

• We should give a clear summary about data and then place the title for them.
• First we may decide how to do a line graph with axis.
• Assign the value to horizontal axis and vertical axis.
• Apply the given data on vertical axis and horizontal axis. These are the basic steps for graph pictures.

Here you can get Statistics Homework Help

Statistics is the art of making effective use of numerical data relating to groups of individuals or experiments. It deals with not only the collection in all aspects,analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments. Now we will see the statistics problems.

Find out the median,mean, mode and the range of these numbers?
14,18,20,27,30.
Solution
The given numbers are 14,18,20,27,30.
Mean
The mean is the average of the given number. with the help of the total value of given numbers we can find the average.
Sum of the given numbers are = 14+18+20+27+30
=109.
Now divide the total value with 5 (5 is the given numbers total) =
= 21.8
Median
Median is the central value of the given number series.
Need help with median formula
The number series is 14,18,20,27,30.
The central value of the above series is 20.
Therefore we can say the median is 20.
Mode
Mode is a duplicate value of the given number series. Here no same value.
So the solution of mode is null or empty.You can avail Free math deal
Range
From the highest value subtract the least value in the series.
Range= 30-14
= 16.

Introduction of learning geometry quadrilaterals :

A learning geometry quadrilateral is the closed figure in a plane formed by four line segments online geometry tutoring. A learning geometry quadrilateral is a plane shape enclosed by four straight lines. Join the lines with opposite vertices are called diagonals of the quadrilateral.

A learning free geometry problems quadrilateral has four vertices, four sides, four angles and two diagonals. In learning geometry quadrilateral, the sum of all angles is 360°.

Types of learning geometry quadrilateral:

• Trapezium
• Parallelogram
• Rhombus
• Rectangle
• Square

Solving math with formula

You have studied about figures of different shapes such as squares,rectangles, triangles and quadrilaterals. You have also calculated perimeters and geometry help free the areas of some of these figures like rectangle, square etc. For instance, you can find the area and the perimeter of the floor of your classroom.

Let us take geometry problems free around the floor along its sides once; the distance we walk is its
perimeter. The size of the floor of the room is its area.

So, if your classroom is rectangular with length 10 m and width 8 m, its perimeter would be 2(10 m + 8 m) = 36 m and its area would be 10 m × 8 m, i.e., 80 m2. Unit of measurement for length or breadth is taken as meter (m) or centimeter (cm) etc. Unit of measurement for area of any plane figure is taken as square metre (m2) or square centimeter (cm2) etc.

Suppose geometry answers free that you are sitting in a triangular garden. How would you find its area?

Area of a triangle =1/2× base × height

Corresponding Angles

Do you know what are Corresponding Angles

In geometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other (see "Measuring angles", below). Where there is no possibility of confusion, the term "angle" is used interchangeably for both the geometric configuration itself and for its angular magnitude. Now let us see about the corresponding angles

Explore your learning skills with GK questions

When two lines are crossed by another one line (which is called the Transversal), the angles in matching corners are called corresponding angles.
The corresponding angles are not necessarily congruent, but if they are the coplanar lines are also parallel. In that, the corresponding angles are congruent, those angles can be used to determine the degrees of the other angles of the parallel lines.

Understand Misleading Graphs

Introduction:
Most of the students usually make two types of errors that show the way to misleading graphs. These errors are made in bar line graphs and in scatter plots. They pertain to the axes of these graphs.

• missing zero
• missing categories

These are the two types of errors. Let us learn the errors in the graphs with some sample examples.

Missing Zero in the Vertical Axis in Misleading Graphs:

In each bar graph, line graph, or scatter plot, the vertical axis must contain the zero. When zero is not revealed, then the vertical axis is supposed to pinch as a wrecked axis to show the absent part of the scale.
Changing the range of scale on the vertical axis clearly distorts the relative lengths of bars in a bar graph, the shape of line in a line graph, or the shape of the "dot cloud" in the scatter plot.

The vertical axis of every double bar graph, line graph, or scatter plot should hold the zero. When zero is not exposed, then the vertical axis is believed to dash as a broken axis to demonstrate the missing part of the range.
