Scientific Calculator
About the Scientific Calculator
A scientific calculator is a useful tool that goes beyond the basic arithmetic of a standard calculator. It includes functions to handle trigonometry, logarithms, exponents, and more complex mathematical expressions. This online version brings that functionality directly to your browser, making it a convenient tool for students, professionals, and anyone needing to perform advanced calculations.
Understanding the Functions
Here is a guide to the key functions available on this calculator. Note that for all trigonometric functions (sin, cos, tan), this calculator operates in degrees.
| Function | Description & Example |
|---|---|
| sin, cos, tan | Core trigonometric functions. Example: sin(30) returns 0.5. |
| log, ln | Base-10 and natural logarithms. Example: log(100) returns 2. |
| xʸ (^) | Exponentiation. Example: 2^3 returns 8. |
| eˣ (exp) | e raised to the power of a number. Example: exp(1) returns ~2.718. |
| √ (sqrt) | Calculates the square root of a number. Example: sqrt(16) returns 4. |
| π, e | Inserts the constants Pi (π ≈ 3.14159) and Euler's number (e ≈ 2.71828). |
Order of Operations
This calculator automatically respects the standard order of operations (PEMDAS/BODMAS). This means that it will perform calculations in the correct sequence: Parentheses, Exponents, Multiplication/Division, and finally Addition/Subtraction. You can use parentheses () to explicitly group parts of your calculation and ensure they are performed first.
