Does this scientific calculator support radians and degrees?

Yes, you can toggle between DEG (degrees) and RAD (radians) mode for all trigonometric calculations.

Can I use physical keyboard keys with this calculator?

Yes, full keyboard inputs (numbers, +, -, *, /, Enter for equal, Backspace for delete) are supported.

This online scientific calculator supports direct physical keyboard navigation as well as mouse and touch input:

Numbers & Arithmetic: Use keys 0–9, +, -, *, /, and Enter or = for immediate computation.
Trigonometry: sin, cos, tan and their inverses (sin⁻¹, cos⁻¹, tan⁻¹). Toggle between Degree (DEG) and Radian (RAD) modes via the top mode button.
Powers & Roots: xʸ (power), √ (square root), ³√ (cube root), and 1/x (reciprocal).
Constants & Factorials: Mathematical constants π (3.14159...) and e (2.71828...), plus n! factorial.
Memory Functions: M+ (add to memory), M- (subtract from memory), and MR (memory recall).
