Free online scientific calculator with advanced mathematical functions. Perform trigonometry (sin, cos, tan), logarithms (log, ln), exponentials (e^x, 10^x), powers (x², x³, xʸ), square roots, and more. Perfect for students, engineers, and professionals.

Scientific Calculator Functions Guide

📐 Basic Arithmetic

Use +, -, ×, ÷ for basic calculations. The calculator follows standard order of operations (PEMDAS).

📊 Trigonometric Functions

sin, cos, tan - Sine, Cosine, Tangent (angle in DEG/RAD/GRAD)
sin⁻¹, cos⁻¹, tan⁻¹ - Inverse trigonometric functions
Example: sin(30°) = 0.5, cos(60°) = 0.5, tan(45°) = 1

📈 Logarithmic & Exponential Functions

log(x) - Base-10 logarithm (log₁₀ x)
ln(x) - Natural logarithm (logₑ x)
eˣ - Exponential function (e raised to power x)
10ˣ - 10 raised to power x
Example: log(100) = 2, ln(e²) = 2

🔢 Power & Root Functions

x² - Square (x × x)
x³ - Cube (x × x × x)
xʸ - Power (x raised to y)
√x - Square root
1/x - Reciprocal
Example: 5² = 25, √25 = 5, 2³ = 8

💡 Tips for Using the Scientific Calculator

• Parentheses: Use ( ) to group expressions and control order of operations.
• Angle Mode: Select DEG for degrees, RAD for radians, or GRAD for gradians before trigonometric calculations.
• Clear (AC): Resets the entire calculation.
• Delete (⌫): Removes the last character entered.
• Keyboard Support: Use your keyboard for faster input (numbers, operators, Enter for =, Backspace for delete, Escape for clear).
