Frequently Asked Questions
What is a scientific calculator?
A scientific calculator is an advanced calculator that supports trigonometric functions (sin, cos, tan), logarithms, powers, roots, factorials, combinations, permutations, and other mathematical operations beyond basic arithmetic. It's essential for students studying mathematics, physics, engineering, and related fields.
Can I use this calculator on my phone?
Yes! This calculator is designed mobile-first with large touch-friendly buttons, responsive layout, and a collapsible scientific panel for comfortable use on any smartphone or tablet. The interface adapts to your screen size automatically.
Does the calculator support degrees and radians?
Yes. You can toggle between DEG (degrees) and RAD (radians) mode at any time using the mode bar at the top of the calculator. Your selected mode is saved automatically and persists across sessions.
Can I calculate factorials?
Yes. Use the n! button in the scientific panel to calculate factorials. For example, 5! = 120 and 10! = 3,628,800. The calculator supports factorials up to 170! to prevent overflow errors.
Can I calculate combinations and permutations?
Yes. Use the nCr button for combinations and nPr for permutations. Enter the first number, then press the function button, then enter the second number. For example, 5 nCr 2 = 10 and 5 nPr 2 = 20.
Does the calculator save calculation history?
Yes. All calculations are automatically saved to your browser's local storage and persist even after you close or refresh the page. You can click any history entry to restore it, delete individual entries, or clear the entire history.
Does this calculator work offline?
Once the page is fully loaded, the calculator works entirely in your browser with no server communication needed. All calculations are performed locally using JavaScript, so you can use it even with a limited internet connection.
