This is an online JavaScript scientific calculator. You can click the buttons or type to perform calculations as you would on a physical calculator.

A scientific calculator is a versatile tool designed to handle a wide range of mathematical operations, beyond the basic arithmetic functions found in standard calculators. Here’s an overview of the primary functions and capabilities of a scientific calculator:

**Addition (+)**: Adds two or more numbers.**Subtraction (-)**: Subtracts one number from another.**Multiplication (Ã—)**: Multiplies two or more numbers.**Division (Ã·)**: Divides one number by another.

**Exponents (x^y)**: Raises a number to the power of another number.**Square Root (âˆšx)**: Finds the square root of a number.**Logarithms (log, ln)**: Calculates the logarithm of a number, with`log`

typically being the base 10 logarithm and`ln`

the natural logarithm (base e).**Factorials (n!)**: Computes the factorial of a number, which is the product of all positive integers up to that number.**Trigonometric Functions (sin, cos, tan, and their inverses)**: Calculates the sine, cosine, and tangent of an angle, as well as their inverses (arcsin, arccos, arctan).

**Degrees and Radians**: Scientific calculators allow you to switch between degrees and radians, which are units of measuring angles. This is particularly useful in trigonometry.

**Exponentiation (EE or EXP)**: This allows you to enter and calculate numbers in scientific notation, useful for very large or very small numbers. For example, 3.5 Ã— 10^8 can be entered as 3.5E8.

**Memory Recall (MR), Memory Store (MS), Memory Add (M+), Memory Subtract (M-)**: These functions let you store and recall values in memory, which can be helpful for multi-step calculations.

**Pi (Ï€)**: Provides the value of Ï€, approximately 3.14159, which is used in various mathematical calculations, especially involving circles.**Euler’s Number (e)**: Represents the constant e, approximately 2.718, used in exponential growth calculations and logarithms.

**( )**: Parentheses are used to group operations and control the order of operations in a calculation, ensuring certain parts of an expression are evaluated first.

**Mean, Standard Deviation, and Variance**: Some scientific calculators offer statistical functions to calculate the mean (average), standard deviation, and variance of a data set.**Data Entry and Editing**: You can enter and edit lists of numbers for statistical analysis.

**Polar to Rectangular and Rectangular to Polar Conversions**: Converts coordinates from polar form (r, Î¸) to rectangular form (x, y), and vice versa.

**i (Imaginary Unit)**: Allows calculations with complex numbers, which include real and imaginary components. Complex numbers are used in advanced mathematics and engineering.

**Fraction (a/b)**: Enables the entry and manipulation of fractions, including conversion between improper fractions and mixed numbers.

**nPr and nCr**: Calculates permutations (nPr) and combinations (nCr), which are used in probability and statistics to determine the number of ways to choose or arrange a subset of items from a larger set.

**Equation Solvers**: Some advanced scientific calculators can solve linear and quadratic equations, and sometimes even more complex equations.

**Program Mode**: On programmable scientific calculators, you can create and store custom programs to automate repetitive calculations.

**Base Conversion**: Converts numbers between different bases (binary, octal, decimal, hexadecimal), which is essential in computer science and digital electronics.

These functions make the scientific calculator an essential tool for students, engineers, scientists, and anyone who needs to perform complex calculations regularly.
