What is Scientific Calculator?
A scientific calculator is an advanced calculator that can perform trigonometric, logarithmic, exponential, and other complex mathematical operations beyond basic arithmetic.
How It Works
Enter expressions using the on-screen keypad or keyboard. The calculator evaluates mathematical expressions following standard order of operations (PEMDAS/BODMAS).
Formula & Calculation Method
Operations: +, -, ×, ÷, sin, cos, tan, log, ln, √, x², x³, xⁿ, π, e, ! (factorial), ( ), and more.
Examples
Scientific Operations

Frequently Asked Questions
Find answers to common questions about this calculator below.
A scientific calculator can perform trigonometric (sin, cos, tan), logarithmic (log, ln), exponential, square root, power, factorial, and other advanced mathematical functions.
Ensure your calculator is in the correct mode (DEG for degrees, RAD for radians). For example, sin(30°) = 0.5 in DEG mode, while sin(30) = -0.988 in RAD mode.
