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:

 Multiplication (×)
 Division (÷)
Trigonometric Functions
 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.
 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.
 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.
 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.
 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.
 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.
