The Advantages of Online Scientific Calculator

!±8± The Advantages of Online Scientific Calculator

In the olden days, people used to calculate using objects and items such as sticks, leaves or even beans. However, this will cause misunderstanding and at times, unfairness would happen because it depends on the honesty of the person who is doing the counting. So, to solve this problem, the inventor had come out with abathia, the first handmade calculator made from wooden frame. There are wires in between which are filled with beads. This wooden calculator has been used by most of the merchants and offices for quite some time for normal and easy calculations. However, the functions are quite limited and only suitable for basic calculations.

As the economy and technology becoming more and more advance, inventors had come out with basic calculator for people to perform exact calculation. Some of the functions such as 'plus', 'minus', 'multiply' and 'divide' were then developed. After that, programmable calculators are invented to perform complicated calculations easily. The latest calculator is called scientific calculator. It has been widely used in universities and companies to ease the calculation processes. Looking at the convenience of scientific calculator, Rolf Howarth came out with the idea to develop online scientific calculator in 1996. Square Box Systems Ltd. became the host companies to support this online site since the launching of the software.

The written online scientific calculator has all the functions such as logarithms, logs to base 2, square root, factorials, trigonometry functions, hexagonal, binary functions and others. Now, let us look into the benefits of this calculator; be it for business use or personal use.

1) Convenience

It is now convenient for people to perform complicated calculations using online scientific calculator. Today, Wi-Fi is available everywhere and as long as you are connected to the Internet, the calculator can be used anytime you prefer.

2) Easy

This online calculator is easy to be used. There is a manual or help function to guide you if you are not sure which buttons to click for your calculations.

3) User friendly Interface

It is not complicated and it has a user friendly interface. All the buttons are well arranged exactly like the normal scientific calculator.

4) All Types of Calculations

This calculator is able to perform any types of calculations. For example, you can use it to calculate your house loans, property taxes, income tax benefits, insurance and many more. It is suitable for business people as well as students.

Finding the population of a city may seem like a daunting task. However, it's a lot simpler that you would think. Use exponents and exponential functions to express large or small numbers written in the scientific notatiion. Using the exponential function f (t) = ab^t you can find the population of any city.

The Linear Function

!±8± The Linear Function

There are many basic functions you will have to learn over the course of your math career. The first and most basic function is the linear function. A linear function is used to describe the relation of a straight line. This can be any straight line, at any angle or in any position. The general form of these functions is as follows;

y = m*x + b

Lets take a look at what all of these terms mean. It will be important to have a thorough understand of what each of them means in a mathematical and graphical sense.

First off we can establish our two variables in this equation x and y. X is the independent variable and it is denoted on the horizontal axis of a graph. Y is the dependent variable (since its value depends on the value of x) and is denoted on the vertical axis of the graph.

The letter 'm' is the slope of the line. Graphically this will give you the angle of the line. The higher the slope, the steeper the angle with the x axis. The slope can be determined from any two point on the line. You must simply sub their values into the following equation;

m = y2 - y1 / (x2 - x1)

This calculation is usually pretty easy and can be done on your calculator.

The last term, b, is the y intercept of the line. This is the point where the line crosses the y axis. If you have a graph of the line you can simply read this value directly from the graph. If you have the slope of the line, you can sub in any point on the line, rearrange, and solve algebraically for the y intercept.

So as you can see the linear function is not extremely complicated. It is a good place to start when learning about functions.
