A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have many more features than a basic four-function calculator, like the ability to calculate trigonometric functions, logarithms, and exponents. Some scientific calculators also have a statistics mode, which allows you to keep track of a list of numbers and calculate statistical operations on them, like mean and standard deviation.

## What Are Scientific Calculators Used For?

Top-quality scientific calculators are used for a variety of tasks. The most common use for a scientific calculator is to calculate mathematical expressions. You can also use scientific calculators to calculate the roots of equations, determine the size of an object, and convert between units of measurement. These calculators, in the classroom, can help students understand concepts.

## How Does a Scientific Calculator Work?

A scientific calculator equips RCL and STO with two key functions. RCL stands for Recall and allows you to recall a previously stored value from the calculator’s memory. STO, on the other hand, stands for Store and allows you to store a value in the calculator’s memory.

You can set your best-rated calculator to scientific mode by pressing the Mode button until the Scientific mode icon displays. This will give you access to all the scientific calculator functions. The symbols on a scientific calculator can vary depending on the make and model, but they usually include the standard mathematical symbols such as +, -, x, /, as well as more advanced functions such as Sin, Cos, Tan, log, and exp.

The function keys on a scientific calculator have labels of the corresponding function, such as Sin, Cos, Tan, log, or exp. These keys allow you to quickly access the most commonly used functions on the calculator. Continue reading to know more about the functionality of these function keys.

## Functionalities of Different Keys in a Scientific Calculator

**STO Key:**The “STO” key on a scientific calculator is used to store a value in memory. This can be useful for storing frequently used values, such as constants, or for storing intermediate results in a longer calculation.**SIN/COS/TAN Key**: It is used to calculate the sine, cosine, and tangent of a number. To use this key, you first enter the number you want to calculate the sine, cosine, or tangent of. Then, you press the SIN/COS/TAN key. The calculator will display the result of the calculation.**HYP Key**: The “hyp” key can calculate the hypotenuse of a right-angled triangle. This is the longest side of the triangle and is also the side opposite the triangle’s right angle. To use the “hyp” key, you first need to input the lengths of the triangle’s other two sides. The calculator will then use the Pythagorean theorem to calculate the hypotenuse.**Recall Key**: The recall key on a scientific calculator can help you retrieve a previously entered number or calculation. To use the recall key, simply press the key and then the number or calculation you want to recall. The calculator will then display the number or calculation you entered.**SQRT Key**: The square root key on a scientific calculator can find the square root of a number. You can do it by pressing the square root key and then entering the number that you want to find the square root of. The square root of a number is the number that when multiplied by itself, equals the original number. For example, the square root of 9 is 3, because 3 multiplied by 3 equals 9.

## Is a scientific calculator the same as a maths calculator?

The answer is No. A scientific calculator is not the same as a maths calculator.

A scientific calculator includes features such as logarithmic and trigonometric functions, complex numbers, graphing, and statistical calculations.

A maths calculator, on the other hand, is typically a basic calculator that you can use for everyday calculations such as addition, subtraction, multiplication, and division.

Although a scientific calculator may be used to perform basic maths calculations, its overall capabilities are far more advanced than those of a basic maths calculator. With a scientific calculator, users can solve higher-level equations, draw graphs and charts, and perform a variety of complex calculations.

## Conclusion

The scientific calculators are a great addition to any student’s backpack during the back-to-school season. They are perfect for any math or science class and can help with any homework or test. They are also a great way to save time and money on calculators for any future classes.
