What Is a Scientific Calculator?

A scientific calculator is an advanced mathematical tool designed to perform complex calculations beyond basic arithmetic. Unlike standard calculators, scientific calculators can handle trigonometric functions, logarithms, exponentials, statistical calculations, and various mathematical operations essential for students, engineers, scientists, and professionals.

Our online scientific calculator provides all the functionality you need in a user-friendly, web-based interface. Whether you're solving homework problems, conducting research, or working on engineering projects, this calculator offers the precision and versatility required for advanced mathematical computations.

Key Features

Basic Arithmetic

Addition, subtraction, multiplication, and division with decimal precision.

Trigonometric Functions

Sin, cos, tan and their inverse functions with degree/radian mode switching.

Logarithmic Operations

Natural logarithm (ln) and common logarithm (log) calculations.

Power Functions

Square root, powers, and exponential calculations including e^x.

Mathematical Constants

Built-in π (pi) and e (Euler's number) for precise calculations.

Advanced Operations

Factorial calculations, percentage operations, and parentheses support.

How to Use the Scientific Calculator

Basic Operations

Enter numbers by clicking the number buttons or typing on your keyboard. Use the standard operator buttons (+, -, ×, ÷) for basic arithmetic. The display shows your input in real-time, and you can see intermediate results as you build complex expressions.

Scientific Functions

For trigonometric calculations, first select your preferred angle mode (DEG for degrees or RAD for radians) using the mode buttons. Then click the desired function (sin, cos, tan) followed by the angle value and closing parenthesis.

Advanced Features

Use parentheses to control the order of operations in complex calculations. The calculator follows standard mathematical precedence rules. Access logarithmic functions (log, ln), square root (√), and power operations easily through dedicated buttons.

Memory and Correction

Use "C" to clear all input, "CE" to clear the current entry, or the backspace button (⌫) to delete the last character. The calculator maintains accuracy throughout multi-step calculations.
