How to Use This Scientific Calculator
Whether you are a student tackling advanced algebra, an engineer solving complex trigonometric equations, or a professional needing quick access to logarithms and roots, our free online Scientific Calculator is designed for speed and precision.
Key Features & Guide:
- Degree vs. Radian Mode: Before calculating trigonometric functions (sin, cos, tan), ensure you have selected the correct angle unit. Click the Deg or Rad toggle at the top right of the calculator. You can even switch modes after typing your equation to instantly convert the answer!
- Inverse Trigonometry: To calculate arcsin, arccos, or arctan, use the sin⁻¹, cos⁻¹, and tan⁻¹ buttons.
- Arbitrary Roots (ʸ√x): To find a specific root (like the 4th root of 16), type the root index first, click the ʸ√x button, and then type your base number. (Example: Type '4', click 'ʸ√x', type '16', and press Calculate to get 2).
- Constants & Factorials: Instantly insert Pi (π) or Euler's number (e) into any equation. Use the n! button to calculate the factorial of any whole number.
Pro Tip for Complex Equations:
This calculator supports implied multiplication and deep parenthesis nesting. Typing
