Why Is Math Important For Our Students?

Today's students must master advanced skills in mathematics, science, and technology to stay on track for college and for promising careers. Mathematics teaches ways of thinking that are essential to work and civic life.

• Students who take algebra and geometry go on to college at much higher rates than those who do not (83% vs. 36%).
  
• Most four-year colleges require three to four years each of high school math and science for admission.
  
• Almost 90% of all new jobs require math skills beyond the high school level.
  
• Entry-level automobile workers must use advanced mathematics formulas to wire a car's electrical circuits.
  
• Strong math skills are needed for understanding graphs, charts, and opinion polls in a newspaper, for calculating house and car payments, and for choosing a long-distance telephone service.

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.

10 Effective Fundamentals For Teaching Math

Teaching math to the students can be a forbidding task for many of the math tutor and parents because math is a different subject compared to other subjects.
