Where Do We Use Calculus In Real Life?

Sometimes it is not necessary that what we learn will directly use in our life. Similarly, we use calculus concepts in daily life indirectly. Calculus used in engineering and construction and so on directly. However, if you are not involved in one of these fields you may not use calculus regularly. But calculus use in all the machines like dishwasher, microwaves and so on. Therefore, indirectly we use it. Below you can find the real use of calculus in brief.

Calculus is a great training for the mind. Calculus helps you to improve logical thinking and allow you to think in ways. Calculus helps in all the way, no matter what career you have chosen.
Calculus has a major use in the medical line. Doctors use calculus concepts to find the growth rate of tumors.
Credit card companies make use of calculus concepts to make minimum payments due on credit cards.
In the Incensing world of technology the calculus has become more useful. Any operation research uses calculus when manufacturing observe the difference. Companies use calculus to improve operating efficiency, increase production, and raise profits and so on.
Calculus concepts also use to learn other subject like physics, mechanical engineering, and electrical engineering, economics and so on.

Biologists use calculus concepts to increase the rate of growth of necessary bacteria and to decrease the unwanted bacteria growth.

Calculus used in the entire science and technology field. In today’s world we all are depending on the technology. Therefore, directly, indirectly we are use calculus daily in our life. Statistics tutors also use calculus to evaluate survey data.

Hope this will assist you to see the actual value of calculus in our life. At least that is all depends on what you define real life as.

How To Do Quadratic Equation Quickly

Are you struggling with the solution of quadratic equation? Then you at right place. Basically quadratic equations are used to find the curve on a Cartesian grid and also used to find the curve of flying objects. For examples, football, baseball, basketball, etc. The general form of the equation is ax^2+bx+c=0, it is a second degree polynomial equation. There are many ways to get solution of a quadratic equation. Keep reading and find how it is possible to solve quadratic equation quickly.

This is one of the easiest ways to solve quadratic equation, but it is not applicable to solve all the quadratic equation.

1) Combine all like term and move them to one side of the equation.

2) Factor the expression. Find the common factors.

3) Set each set of parenthesis equal to zero and solve.

Example: 2x^2-8x-4=3x-x^2


3x(x-4) +1(x-4) =0
(x - 4)(3x + 1)=0


x-4=0 or 3x+1=0

So, x=4 or x= -1/3

Quadratic Formula:

Sometimes quadratic equations are too messy and factoring method may not always be successful, but the quadratic formula can always find the solution.

1) Combine all like term and move them to one side of the equation.

2) Write down quadratic formula x= [-b±√ (b^2-4ac)]/ [2a].

3) Identify the values of a, b and c in the quadratic equation and substitute into the formula.

4) Simplify the square root and do the calculation.

Example: 4x^2-5x-13=x^2-5


Step2: x = [-b±√ (b^2-4ac)]/ [2a]

Step3: Compare equation with ax^2+bx+c=0

So, a=3, b= -5 and c=8

Step4: x= [5±√ ((-5)^2-4*3*8)]/ [2*3]

So, x=1/6[5±i√71]

Through Online Math Tutoring you can solve quadratic equation quickly and also you can get help with solving any complex problem within a short time. Follow these easy steps to solve complex quadratic equation quickly. To know more about quadratic equation take online algebra tutor help.

8 Math Equations Used In Our Life

When you start learning math equations, one question defiantly arise in everybody’s mind. That is, why do we have to learn math equations? What is the real use of these equations? Math is all around us and we use it in daily life. It has shaped our understanding of the world in uncountable ways. Math is all depends on equations and we use math skills in our life very often. Below you can find more about 8 wonderful equations that have formed mathematics and our life.

1) The Pythagorean Theorem:

The great Pythagorean Theorem is the foundation of understanding geometry and it helps us in many real life applications. This equation describes the relation between the sides of a right triangle. The Pythagorean Theorem equation is,”a^2+b^2=c^2”. Get more examples on Pythagorean Theorem on Online Geometry Tutoring.

2) Euler's equation:

This equation describes about the nature of spheres. , Let F be the number of faces, E the number of edges and V the number of vertices, then you will always get V – E + F = 2, when you cut the surface of a sphere up into faces, edges and vertices.

3) Logarithms:

Logarithms are the base of digital technology. It is the most common way to multiply large numbers quickly. Basically logarithms are the invers of the exponential functions. For example, log_10 (1) =0, since 10^0=1. Logarithm concepts are basically used in calculator, computers and other digital machines.

4) Derivation:

Derivation (the rate of change) is possible with calculus, and Calculus Tutor will help you through the topics of Calculus. We have many calculus derivative formulas which allow us to measure the rate at which a quantity is changing.

5) Law of gravity:

The whole world depends on gravitation.
Newton's describes the force of gravity between two objects in terms of a universal constant, G, the masses of the two objects is definite as m1 and m2 and the distance between the two objects is d. law of gravity is denoted by F.
F=G (m1*m1)/d^2  

6) Quadratic equations:

This equation allows us to find the roots of the equation, if the highest exponent of the variable is a square. It is usually written as ax^2+bx+c=0. The quadratic formula for this equation is,
x= [-b±√ (b^2-4ac)]/ [2a]

7) Wave equation:

This is the most common equation we use in our life without knowing.  This equation commonly used in music. The wave equation describes the behavior of the waves.

8) Fourier Transformation:

This equation is the complex wave equation. Fourier transformation is used to record the messy conversation of human. This equation allows combining the number of ways into one single wave. Also used in data compression and so on.
Hope you understand the use of these 8 wonderful equations in our life.

Teaching Kids Why Math Matters?

Day in and day out, math teachers hear the same question: “Why do I need to learn this?” Math teacher Peter Caryotakis has two answers for his students. “Because someday your children will ask you for help with their homework,” is his funny (but accurate) reply.  He follows up with a more serious answer: “Because knowing math will keep as many doors as possible open in your future.”
Math teachers all over the country have their favorite answers to this timeless question, reasons that demonstrate why math matters. In a nutshell, these reasons can be summed up by three words: Personal, Practical, and Patriotic.
Personal Reasons to Learn Math:
A person's success in life depends on how well she can solve problems. No matter what her career or life situation, she’ll find satisfaction and reward by knowing how to tackle challenges head on. And while kids can’t possibly practice every problem they’ll ever have in life, there is a class in school that can help them learn how to think logically: math. Doing a math problem helps practice the problem-solving steps that apply to everyday situations: define the problem, think of ways to solve it, implement a solution, and evaluate the results.
