The Algebraic Topology


Differential forms in algebraic topology: - The mathematical study of shapes and also the areas is named the topology. The properties such as connectedness, continuity and boundary are related to the topology. Algebraic topology tries to live degrees of property exploitation algebraic constructs like similarity and homotopy groups. Topology developed as a field of study out of geometry and set theory, through analysis of such ideas as house, dimension, and transformation.



Differential form in algebraic topology is that the field managing differentiable functions on differentiable manifolds. It’s closely associated with differential geometry and along they create up the geometric theory of differentiable manifolds. Differential Forms in algebraically Topology makes an endeavor to clarify the many attention-grabbing and necessary connections between differential forms and algebraically topology.

Algebraic Equation : -
An equation could be a statement that 2 pure mathematics expressions are equal. The elements of an equation separated by the sign of equality are known as members or sides of the equation, and are distinguished because the right facet and therefore the left facet.  If the 2 expressions are continually equal, for any values we have a tendency to provide to the symbols, the equation is named a regular equation, are concisely an identity. So the equation is higher than an identity, as well seen by grouping the terms on the left facet. If 2 expressions are solely equal for a selected price or valves of the symbols, the equation is named an equation of condition, or additional typically an equation. This, then is an equation is that the unremarkable sense of the term, and therefore the valve three is alleged to satisfy the equation. The method of finding its valve is named resolution the equation.

The worth is named root of the equation. To unravel an issue algebraically we have a tendency to initial build an equation on the idea of the conditions of the given question. For this we've got to use one variable or additional variables. Therefore solve a given question, by 3 steps. Build an assumption employing a variable x. Construct an equation in terms of x by reading the question rigorously. Solve the equation. The Process of finding an easy Equation resolution of an easy equation depends solely on the subsequent axioms.

If to equal we have a tendency to add equals the sums square measure equal. If from equals we have a tendency to take equals the remainders square measure equal. If equals square measure increased by equals the merchandise square measure equal. If equals square measure divided by equals the quotients square measure equal.

Example: - to unravel the equation eight x = thirty two dividing each side by eight we have a tendency to get x = four.

Example: - To solve the equation 3x/4 = -3 multiplying by four each side we have a tendency to get 3x = - 12, dividing by three each side we have a tendency to get x = -4. Represent the unknown amount by an emblem x, and specific in symbolical language the conditions of the equation, we have a tendency to therefore get an easy equation.

Mathematics, How It Changed Human Life Style?




Mathematics it’s only subject which can judge people’s attitude in life. Either it can attract a child or make him or her fearful to avoid complexity of unsolved problem. From here it shows how someone wants to treat life when the real and complex problems appear. Find below how can math change human life.


If you look at anything around the world which developed from human being you can directly relate mathematics with that.

Look at the Computer which earlier serves the purpose of some specific area is now part of day to day life. You can connect live tutor chat threw social networks or from any other source and plenty of other useful application which changed human life drastically.

It is forcing us to think how exactly it happened? It’s just because of mathematics. Base of all the computer application is logic's and base of logic is mathematics. Now who doesn’t love mathematics still engaged with it indirectly by using it in day to day life.

Now everything is available on Google or other search engine. Everything is running on logic here also and all these logic's are bunch of mathematics formulas. Post internet existing life changed a lot now world is inside a box which can be any device computers, tablet or smart phones.

These days’ students start loving to solve math problems which are either complex or unsolved because of free math help hotline 24/7 and also that is only area of opportunity where next generation is working.

Without mathematics it is almost tough to think worlds so accessible. Just imagine listening voice and seeing your lovable ones who is 2000 miles away from you can give you a wonderful feelings.

Each and every imagination is possible only because of mathematics. We should thanks mathematics for making our life so flexible and easy. Many more imagination is waiting and many more genius is there to work passionately on those. This is how mathematics changed human life style.

Area of Triangle


                                                                                                     
The closed figure that is formed by least the number of line segments that is three line segments is known as a triangle. There are different types of triangles that are classifies on the basis of their sides and angles.



The triangles are that classified on the basis of lengths of the sides are

(i) Scalene
(ii) Isosceles
(iii) Equilateral

The triangles are that classified on the basis of the measures of their angles are

(i) Acute angled
(ii) Right angled
(iii) Obtuse angled

Online Geometry Tutoring helps you to solve all the homework problems

Scalene Right Triangle

A scalene right triangle is a three sided figure in which all the three sides are different from each other and one of the angle measures 90 degrees.

Finding Area of a Triangle

Area of any three sided figure (triangle) is the region that is enclosed by the three sides of the figure. This can be found using different formula.

Formula : 1

Area = ½ * base * height
Where base is the side on which the altitude is drawn, height is the length of the altitude that is drawn on the corresponding base.

Example : 1

Find the area of the figure given below.

Solution :

In the given figure, we see that the altitude AD is drawn on to the side BC of the triangle. Therefore, Base = BC = 8 cm and height = AD = 3 cm.

We know, area = ½ * base * height
                            = ½ * 8 * 3
                            = ½ * 24
                            = 12 square cm


Example : 2

Find the area of a three sided figure whose sides lengths are 4 cm, 5 cm and 3 cm.

Solution :

Given, the three sides are
1st side = 4 cm
2nd side = 3 cm
3rd side = 5 cm

These three sides form a Pythagorean triplet. In which 4 cm and 3 cm are the lengths of the legs (that is the sides containing the right angle)

Therefore, Base = 4 cm and height = 3 cm.
We know, area = ½ * base * height
                        = ½ * 4 * 3
                        = ½ * 12
                        = 6 square cm

Formula : 2

If a, b and c are the lengths of all the sides of a triangle then its area is found using the formula
Area = square of root of [s(s – a)(s – b)(s – c)] square units

Where S is known as the semi perimeter and is found by sum of the side lengths divided by 2


Example : 3


Find the area of the triangle whose sides lengths are 6 cm, 7 cm and 9 cm


Solution :


Let a = 6 cm, b = 7 cm and c = 9 cm

Semi perimeter = (a + b + c)/2 = (6 + 7 + 9)/2 = 22/2 = 11 cm
s – a = 11 – 6 = 5
s – b = 11 – 7 = 4
s – c = 11 – 9 = 2

Area = √[s(s – a)(s – b)(s – c)] square units
Area = √[11(5)(4)(2)] square cm
Area = √[440] square cm
Area = 20.78 square cm


Example : 4


Find the area of the triangle whose sides lengths are 10 cm, 12 cm and 14 cm


Solution :


Let a = 10 cm, b = 12 cm and c = 14 cm

Semi perimeter = (a + b + c)/2 = (10 + 12 + 14)/2 = 36/2 = 18 cm
s – a = 18 – 10 = 8
s – b = 18 – 12 = 6
s – c = 18 – 14 = 4

Area = √[s(s – a)(s – b)(s – c)] square units
Area = √[18(8)(6)(4)] square cm
Area = √[3456] square cm
Area = 58.79 square cm


Formula : 3


If all the sides of the three sided figure are congruent to each other. Then such a figure is known as equilateral triangle.

Area = (√3/4)(a2) square units.
