Home › Scientific Calculator
Free online scientific calculator with trigonometry, logarithms, exponents, factorials, and memory functions.
The scientific calculator evaluates expressions involving trigonometry, logarithms, exponents, factorials, and constants like π and e. It supports nested parentheses and standard operator precedence, so a long formula entered in one line returns the correct value.
Students in algebra, geometry, trigonometry, calculus, physics, and chemistry, plus engineers, scientists, and statisticians at work. Test-takers preparing for the SAT, ACT, or technical certifications also use one daily.
It handles formulas that a basic calculator cannot, such as compound trigonometric expressions, exponential decay, and combinatorial counts. It also catches missing parentheses by enforcing precedence rules consistently.
It answers questions like "What is e raised to the 2.3 power?", "What is the cosine of 73 degrees?", and "What is the value of (3.5² + 4.1²) under a square root?"
