How to Use the Scientific Calculator

Our scientific calculator provides advanced mathematical functionality with comprehensive scientific functions:

🔬 Scientific Functions

Access trigonometric functions (sin, cos, tan), logarithmic functions (ln, log), power operations (x², √, x^y), factorial calculations (!), and exponential functions (eˣ). Use the 2nd button to access inverse functions.

📐 Angle Modes

DEG (Degrees): Standard 360° system for everyday calculations
RAD (Radians): Mathematical π system for calculus and advanced math
GRAD (Gradians): 400 grad system for surveying applications

🧮 Mathematical Constants

π (Pi): Mathematical constant approximately 3.14159
e (Euler's number): Mathematical constant approximately 2.71828
Ans: Recall the last calculated result for use in new calculations

💡 Pro Tips

• Use parentheses for complex expressions
• Switch angle modes using DEG/RAD/GRAD buttons
• Press 2nd to access inverse trigonometric functions
• Keyboard input supported for faster calculations
• All calculations support high precision decimal numbers

Frequently Asked Questions

Use the DEG/RAD/GRAD buttons above the calculator. DEG is for degrees (360°), RAD is for radians (2π), and GRAD is for gradians (400 grad). The active mode is highlighted.
The 2nd button toggles secondary functions. When pressed, trigonometric functions change to their inverse (sin becomes sin⁻¹, cos becomes cos⁻¹, tan becomes tan⁻¹).
Yes! Use number keys 0-9, operators (+, -, *, /), decimal point (.), parentheses (), Enter for equals, and Escape for clear. This makes calculations much faster.
Our calculator uses JavaScript's built-in mathematical functions with high precision (typically 15-17 significant digits). Very large or small numbers are displayed in scientific notation.
ln is the natural logarithm (base e ≈ 2.718), while log is the common logarithm (base 10). Natural logarithms are used in calculus and exponential calculations.
