What Is A Scientific Calculator

The electronic calculator has been around for centuries, and have improved over time. But the first scientific calculator was invented and made available to everyone within the last decade, back in 1968.

These devices are now commonplace in classrooms around the world. But what do they actually mean?

Also, how are these calculators different from the basic ones?

I've described the history of the tool and uses, as well as special functions and the difference between regular and scientific calculators in this post to help you begin using the tool.

What is a Scientific Calculator?

Scientific calculators are electronic calculators packed with functions to help solve science, engineering, and maths-related issues.

The calculators allow users to solve trigonometry problems using the built-in trigonometric, inverted, or hyperbolic calculations. In addition, users can work with degrees, radians, as well as grads by simply switching between modes. Additionally, mathematical constants such as Pi as well as Euler's continuous are integrated into these calculators to allow precise calculations.

The devices are also able to work using logs, exponents, and scientific notations, which makes the ideal tools to tackle engineering challenges.

The majority of the calculators available for purchase are handheld. But, they weren't made for use on the go until 1972, four years after they were first released.

When Hewlett Packard was the first company to make scientific calculators available to masses, Texas Instruments took control of a large chunk of the market following the introduction of the SR-50 calculator in 1974. The TI-30 series is among the most well-known series of technological calculators, even to this day.

Types of Scientific Calculators

There are four main kinds of scientific calculators: traditional scientists' calculators, software-based calculators and online scientific calculators.

Regular scientific calculators come with the lowest resolution screen and can't draw coordinates.

Graphic calculators have high-resolution screens that allow users to visualize functions, plot and even plot the coordinates in the blink of an eye.

Software-based calculators are embedded in many operating systems. For instance for instance, the Windows 10 scientific calculator has the majority of functions you require as seen in the screenshot:

Online calculators are, in my opinion, the easiest to utilize. Meta-Calculator.com gives all the features that are available in costly graphic calculators accessible for free. The most appealing aspect is that it is accessible it from anywhere, anytime.

What is the Difference Between Scientific and Regular Calculators?

Apart from scientific calculators, there are two different types of calculators: business and basic calculators.

The calculators can only perform fundamental functions, including addition subtraction, multiplication and division. The calculators aren't able to do operations like logarithms and work with trigonometrics and exponents. h

Basic and business calculators also don't accept nor output any scientific notes, and do not have any storage space to save numbers. Storage is an important feature for math and science classes, as many problems have long solutions, and numbers might need to be repeatedly used.

Other distinctions between scientific calculators and regular calculators include:

  1. Scientific calculators feature large screens, usually with high resolution. Business and regular calculators have small screens.
  2. Scientific calculators are capable of creating graphs of their functions. However, simple calculators cannot be used for anything other than basic math.
  3. Simple calculators can be inexpensive While scientific calculators are expensive.
  4. Scientific calculators follow operator precedence, but other calculators do not -- more on this below.

Let's say you wish to calculate 4 +6 * 5. If you enter the formula in a basic calculator, the result could be 50.

If, however, you type this same expression in an electronic calculator, the answer would have to be 33 (the most correct solution).

Scientific calculators operate according to the order of operations - division is performed first before multiplication, followed by addition the third time, and then subtraction at the final.

To obtain the right result using a business or regular calculator, you'll have to add parenthesis to the appropriate places. This is not necessary when using scientific calculators.

What Special Functions Do Scientific Calculators Have?

The majority of business and regular calculators can perform four to five functions at a minimum. On the other hand, a science calculator could have hundreds of features.

Although the functions offered by scientific calculators may differ by manufacturer and model, the vast majority of scientific calculators can:

  • Take and print scientific note-taking;
  • Use floating-point arithmetic
  • Use log functions with base 10 and base e;
  • Use exponential functions to work;
  • Be sure to provide accurate values for root functions beyond square roots;
  • Provide quick access to precise Pi and e values; and
  • Utilize trigonometric functions and hyperbolic function.

High-end scientific calculators are packed with even more features which are the most prominent of which are:

  • Working with complex numbers;
  • The embedded cursor controls allow for simple editing of equations
  • Hexadecimal or binary octal number compatibility;
  • Calculations using matrices
  • Calculus compatibility;
  • Fractions compatibility as well as
  • Ability to conduct statistics and probabilities calculations.

Some scientific calculators are programmable and some perform unit conversion (calculations like Celsius conversion to Fahrenheit) and can work with physical constants.

Special Buttons

In order to allow users to complete the operations mentioned above scientific calculators are equipped with specific buttons. The Casio FX-991EX ClassWiz calculator is one of the most well-known scientific calculators. Let's examine its keys and the way they function.

The most basic keys used in this calculator are confined to the lower. Over these keys, a pool of function keys enables the users to complete a range of critical tasks.

The cos, sin, and tan keys make for easy trigonometric calculations. Pressing the SHIFT button allows users to make use of the function that is marked on each key.

Pressing the shift key on the left-hand side of the calculator lets the user utilize inverse sin cos and Tan functions.

The keys on the 2nd row the calculator permit working with fractions, finding square roots, squaring numbers, discovering exponents of numbers and much more.

Log base 10 and base e is attainable using the two keys that are that are on the 2nd row.

The calculator is able to perform many additional functions - like working with scientific notations, identifying negatives of numbers and much more.

The best way to know what a calculator that is scientifically designed is capable of doing is to read its manual. You can download it off the internet prior to purchasing or even read the manual which comes with the gadget.

How to Use Special Keys?

In order to use the various applications that the scientific calculators can provide it is necessary to understand the proper way to enter the numbers. That is you must recognize which keys you have to press prior to and after entering the number(s) that you would like to work with.

Here are some examples to take into consideration:

  • Square root: Pressing the square root button after entering the number will result in the square root symbol visible on the display. To calculate, for instance, that the 9th square root you must press the square root icon first, and then input the number 9 into the calculator.
  • 10.x :For you to find the value of 10 for the power of x you will have to press the 10x button before entering"x" "x" value.
  • 2 :If you want to find the square of the number it is necessary to enter the number you want to square prior to pressing the x2 button.
  • "x-1" :The inverse function works similarly to that of the square. You must enter the number you wish to inverse prior to hitting the button.
  • trigonometric function: It is easy to understand that the operation must be punched in first before entering any numbers. Important to keep in mind is that scientific calculators allow you to work with radians as well as degrees.
  • You can alter the shape you want the results to appear by going in the MODE menu and changing the option that the calculator is placed to display in. The indicator on the upper right of your screen should inform you of what format you're currently working in.
  • Restoring and saving: As I mentioned earlier Math and science-related problems could require lengthy solutions as well as storing and restoring results becomes critical for solving these problems swiftly. There are two ways to make use of calculator storage:
    • You can use"Answer" or the "Answer" function to bring to the exact number or result last displayed on the screen. For instance, if , for example, you calculated the 33 value prior to entering "-10" into the calculator to subtract ten off the result.
    • An alternative method to keep track of the results is to get the answerby pressing the STO button after which press select the ALPHA button, and finally press a key with a letter over it. Entering the key will save the answer to the letter. Then, you can use the letter as a placeholder to store that number.

Conclusion

The ability to use a scientific calculator can help you work through problems quickly - in practice and exams.

Once you've figured out what the tool is and how it works then you can try your hand at using it to tackle problems. The most effective and fastest approach to achieve this is to utilize
