What Is a Scientific Calculator?
This online scientific calculator supports standard arithmetic plus common scientific functions — trigonometry, logarithms, exponents, square roots, and constants like π and e — all running directly in your browser.
How to Use the Scientific Calculator
- Click buttons to enter numbers and operations, just like a physical calculator.
- Use function buttons (sin, cos, log, √, etc.) for scientific operations.
- Press "=" to see your result; your recent calculations are saved in the history panel.
Supported Functions
| Function | Description |
|---|---|
| sin, cos, tan | Trigonometric functions (in degrees) |
| log | Base-10 logarithm |
| ln | Natural logarithm (base e) |
| √ | Square root |
| x² | Square |
| xʸ | Exponent (x to the power of y) |
| π, e | Mathematical constants |
| 1/x | Reciprocal |
Worked Example

Tips for Using This Calculator
- Trigonometric functions here use degrees, not radians, matching most everyday and classroom use.
- Use parentheses to control the order of operations for complex expressions.
- Your calculation history is kept for the current session so you can reference earlier results.
Common Mistakes to Avoid
- Forgetting that trig functions here expect degrees, not radians, if you're used to a radians-based calculator.
- Not using parentheses when an expression needs a specific order of operations.
Frequently Asked Questions
Trigonometric functions (sin, cos, tan) use degrees by default, matching most everyday and classroom calculator conventions.
Yes — use the parentheses buttons to group operations and control calculation order, just like a standard scientific calculator.
No — history is kept only for your current browser session and is not stored on any server or saved after you close the page.
"log" calculates the base-10 logarithm, while "ln" calculates the natural logarithm (base e, approximately 2.71828).
Yes — it's fully responsive and works on both desktop and mobile browsers.
