Online Scientific Calculator
A fully featured, responsive scientific calculator engineered for students, engineers, and researchers with keyboard shortcuts and history tape.
Key Features:
- Trigonometric functions (sin, cos, tan, arcsin, arccos, arctan).
- Natural log (ln), common log (log10), exp, and arbitrary powers.
- Parentheses and strict order of operations (PEMDAS).
- Calculation history tape.
How to Use:
- Use on-screen buttons or your physical keyboard to enter expressions.
- Switch between DEG (degrees) and RAD (radians) for trigonometry.
- Use parentheses for compound arithmetic orders of operation.
- Press '=' or Enter to evaluate.
Using Degrees vs Radians
Make sure your angle mode is configured appropriately: Degrees for standard geometry and surveying; Radians for calculus and advanced physics.
