Full scientific calculator with trig, logs, and more
A full-featured scientific calculator with trigonometric functions, logarithms, exponents, factorial, square root, cube root, and more. Toggle between degrees and radians. Supports keyboard input. Runs entirely in your browser.
A scientific calculator handles mathematical operations beyond basic arithmetic — trigonometry, logarithms, exponents, factorials, and more. This web-based version provides the same functionality as a physical TI or Casio scientific calculator, accessible from any device. It supports standard mathematical notation, parenthesized expressions, and maintains a calculation history. Common uses include homework, engineering calculations, physics problems, statistical computations, and quick conversions. The calculator follows proper order of operations (PEMDAS/BODMAS) and handles edge cases like division by zero and invalid inputs gracefully. All computation runs locally in your browser.
Yes — the calculator follows standard mathematical order: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). This is PEMDAS/BODMAS order, same as physical scientific calculators.
Use degrees for everyday angles (90° is a right angle). Use radians for calculus, physics, and advanced math (π/2 is a right angle). The calculator defaults to degrees — toggle to radians when needed for mathematical computations.
It represents Euler's number e ≈ 2.71828, the base of natural logarithms. It appears throughout mathematics, especially in calculus, compound interest (continuous compounding), and exponential growth/decay formulas.
Yes — type numbers and operators directly. Common shortcuts: * for multiplication, / for division, ^ for exponents, Enter to evaluate. Parentheses work as expected for grouping expressions.
Check if you're in radians mode — sin(90 radians) ≈ 0.894. Switch to degrees mode for sin(90°) = 1. This is the most common scientific calculator mistake.
