Scientific Calculator

A scientific calculator is an advanced online tool that performs complex mathematical operations beyond basic arithmetic, including trigonometric functions (sin, cos, tan), logarithms, exponentials, roots, powers, and more. Whether you're solving physics problems, engineering calculations, chemistry formulas, or advanced mathematics, our scientific calculator provides all functions needed for academic and professional work.

This calculator supports degrees and radians modes for trigonometry, common and natural logarithms (log, ln), exponential functions (e^x, 10^x), powers and roots (x², √x, x^y, ³√x), parentheses for order of operations, constants (π, e), and memory functions. It displays calculation history and handles both simple and complex multi-step calculations.

Advanced mathematics and science require functions unavailable on basic calculators. Students taking algebra, trigonometry, calculus, physics, chemistry, and engineering courses need scientific calculators for homework, exams, and labs. Without access to trigonometric functions, logarithms, and exponential operations, solving these problems requires time-consuming manual calculations or lookup tables.

Professionals including engineers, physicists, chemists, statisticians, and financial analysts use scientific calculators for daily calculations in their work. Scientists benefit from having trigonometric and logarithmic functions readily available for data analysis, research calculations, and experimental design. Students studying for standardized tests (SAT, ACT, AP exams) need scientific calculator proficiency.

The tool ensures accuracy using standard mathematical libraries, provides instant results for complex calculations, and allows switching between degrees and radians for trigonometry. It's particularly valuable when completing homework without a physical calculator, double-checking exam answers, performing quick calculations during lectures, or working on computer-based assignments.

Physics Calculations: Calculate angles, forces, projectile motion, wave properties, and energy using trigonometric and exponential functions.

Chemistry Problems: Compute pH, molarity, reaction rates, and exponential decay using logarithmic and exponential functions.

Engineering Math: Solve trigonometric problems in structural analysis, electrical engineering, and mechanical design calculations.

Statistics: Calculate standard deviations, probabilities, and exponential distributions using advanced mathematical functions.

Geometry & Trigonometry: Solve triangle problems, find arc lengths, calculate areas, and work with angles in degrees or radians.

Using our scientific calculator is intuitive: enter numbers using the number pad, click operation buttons for functions (sin, cos, log, etc.), use parentheses for complex expressions, and press equals or enter to calculate. Switch between degree and radian modes for trigonometry. Clear individual entries or all calculations as needed.

Common functions: sin(30°) = 0.5, cos(60°) = 0.5, tan(45°) = 1, log(100) = 2, ln(e) = 1, e^1 ≈ 2.718, 10^2 = 100, √16 = 4, 2^3 = 8. Order of operations follows PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction). For example: 2 + 3 × 4 = 14 (not 20), but (2 + 3) × 4 = 20. Trigonometric functions in radians: sin(π/2) = 1, cos(π) = -1. All calculations are performed locally in your browser for privacy.
