What Are the Functions of the Scientific Calculator Online?

Calculators are powerful tools that help us perform various mathematical calculations quickly and accurately. Whether it’s for simple arithmetic or complex scientific calculations, calculators provide a wide range of functions to meet our mathematical needs. In this blog post, we will explore the functions available on a Scientific Calculator Online and understand how they can be used.

Basic Arithmetic Operations

Let’s start with the basic arithmetic operations that every calculator offers:

  1. Addition (+)
  2. Subtraction (-)
  3. Multiplication (×)
  4. Division (÷)

Trigonometric Functions

  1. Sine (sin): This function calculates the sine of an angle. The user can input an angle in degrees or radians, and the calculator will return the corresponding sine value.
  2. Cosine (cos): This function calculates the cosine of an angle. Similar to the sine function, the user can input an angle in degrees or radians, and the calculator will return the corresponding cosine value.
  3. Tangent (tan): This function calculates the tangent of an angle. Once again, the user can input an angle in degrees or radians, and the calculator will return the corresponding tangent value.
  4. Arcsine (sin-1 or asin): The arcsine function, denoted as sin-1 or asin, calculates the angle (in degrees or radians) whose sine equals a given value. The input of arcsin(x) must be within the range of -1 to 1. The output of arcsin(x) is always between -π/2 and π/2 in radians. In terms of domain and range, arcsin(x) has a domain of [-1, 1] and a range of [-π/2, π/2]. This function is commonly used to find an angle when the sine value is known.
  5. Arccosine (cos-1 or acos): The arccosine function, denoted as cos-1 or acos, calculates the angle (in degrees or radians) whose cosine equals a given value. The input of arccos(x) must be within the range of -1 to 1. The output of arccos(x) is always between 0 and π in radians. In terms of domain and range, arccos(x) has a domain of [-1, 1] and a range of [0, π]. This function is commonly used to find an angle when the cosine value is known.
  6. Arctangent (tan-1 or atan): The arctangent function, denoted as tan-1 or atan, calculates the angle (in degrees or radians) whose tangent equals a given value. The input of arctan(x) can take any real number as it has a range of (-∞, ∞). The output of arctan(x) is always between -π/2 and π/2 in radians or -90° and 90° in degrees.

These trigonometric functions can be calculated in degrees or radians, depending on the mode selected by the calculator.

Exponential and Logarithmic Functions

Exponential and logarithmic functions are used in various mathematical and scientific calculations. Calculators often provide functions for these operations:

  1. Exponentiation (x^y) 
  2. Square (x^2) 
  3. Cube (x^3) 
  4. Square Root (√x) 
  5. Cube Root (3√x)
  6. nTh Root (n√x)

  8. Common Logarithm (log): The common logarithm function calculates the logarithm of a number to the base 10.

Other Functions

In addition to the basic arithmetic, trigonometric, exponential, and logarithmic functions, calculators often provide several other useful functions. Here are a few examples:

  1. Percentage (%): The percentage function calculates a percentage of a given number.
  2. Pi (π): The pi function represents the mathematical constant π, which is approximately equal to 3.14159. It is widely used in geometry and trigonometry.
  3. Euler’s Number (e): Euler’s number, denoted by the letter “e,” is a mathematical constant approximately equal to 2.71828. It is often used in exponential and logarithmic calculations.
  4. Factorial (!): The factorial function calculates the product of all positive integers up to a given number.
  5. Gamma (Γ): The gamma function is a mathematical extension of the factorial function. It calculates the value of factorial for non-integer numbers. The gamma function is denoted by the Greek letter Γ.
  6. 10x: The 10x function raises 10 to a given power, useful for calculations involving powers of 10.

Additional Buttons on the Calculator

In addition to the functions we discussed earlier, online calculators often include several other buttons that serve specific purposes. Let’s explore these buttons:

  2. AC (All Clear): The “AC” button performs an all-clear function. When pressed, it clears the display and any pending calculations, resetting the calculator to its initial state.
  3. Backspace (←): The backspace button, often represented by a left-pointing arrow (←), allows you to delete the last entered digit or character. It comes in handy when you make a mistake while entering a number or expression.
  4. Equals (=): The equals button (=) is used to perform the calculation and obtain the result. When pressed, it evaluates the entered expression and displays the calculated value on the screen.

Breaking down the steps:

  • ⇒ sin(30+log(10)
  • ⇒ sin(30+log(10), where log(10) equals 1
  • ⇒ sin(30+1)
  • ⇒ sin(31)

Example: 5 – (-6) = 11
Example: (-5) – 6 = -11
sin(30) – log(10) = -0.5
log(10) – sin(30)= 0.5
Multiplication (×)
To multiply two numbers or functions, you can follow the same steps as addition, but with a sign change.Example: 5 × 6 = 30
Example: 5 × (-6) = -30
Example: (-5) × 6 = -30
sin(30) × log(10) = 0.5 × 1= 0.5
log(10) × (-sin(30))= 1×(-0.5) = 0.5
 Division (÷)
To divide two numbers or functions, you can follow similar steps as mentioned for addition and multiplication, but with a sign changeExample: 30 ÷ 6 = 5
Example: 30 ÷ (-6) = -5
Example: (-30) ÷ 6 = -5
log(10) ÷ (-sin(30))= 1÷(-0.5) = -2
