Question

what will the this formula help us in real life exept in getting macks in exams. why we study them?Not only this there are many.

Answer 1

HEY THESE FORMULAES WILL MAKE YOUR CALCULATION STRONG AND WILL MAKE YOUR MIND CUNNING IN MATHS.

Answer 2

Solution :

First of all before going to answer such question let me tell what actually we can do actually with all formulas

• You can do anything , anytime through formulas
• Not a logical to think like that , right . But no it is 100% logical
• So , Let take examples of some of the formulas you have given in the attachment of your question

Use of$(a + b)^2 = a^2 + b^2 + 2ab$ in real life

• Open your Mathematics or any other book very front page of the any lesson or chapter whatever you want to open

• So , you written this formulas in a page , right .

Let the two dimensions of the page be x unit . So it is (x)^2 or we can also say that ( a + b)^2 .

• Let Area A be the chapter number ( Given in the very starting of the chapter  )
• Let Area B be the Chapter Heading
• Let Area C for the the Introduction part of the chapter
• Let Area D for the main body of the chapter

Here , Dimension x = ( a + b )

Implies , x is divided into two parts one is a and other one is b

Therefore , We can say that

Area A + Area  B + Area  C + Area  D = ( a + b)^2 which covers your whole page of any of the textbooks

Overall , What We can do with the formula is we can broken down anything into simpler one

Use of Quadratic Formula which is given by Sridharacharya

⇒ x = −b ± √(b2 − 4ac) 2a.

Introduction :

In C.E. 1025 Sridharacharya derived a formula , which is now known as the quadratic formula for solving a quadratic equation by the method of completing the square

Uses of the Quadratic in our day to day life

When you travel through boat and want to calculate the boat speed when your boat speedometer is not working and you know the time for upstream and downstream

Like that , there are many others uses of the formulas

Marks is not everything in mathematics but it is very much important . The Principle of mathematics is to learn different things  . The all formulas is connected with our day to day life and we derived  them from our real life .
