Scientific Calculator computes a full scientific calculator with trigonometry, logarithms, powers and parentheses. Formula: Direct evaluation of the entered expression using standard operator precedence. Example: To find sin(30°), switch to DEG, press 3, 0, then sin) — or type sin(30).
This calculator evaluates expressions with standard mathematical precedence: parentheses first, then functions like sin, cos, tan, log and ln, then powers and roots, then multiplication and division, and finally addition and subtraction.
Trigonometric functions use radians by default; switch the DRG toggle to degrees if you are working with everyday angles. The constant buttons π (≈3.14159) and e (≈2.71828) insert precise values rather than rounded ones.
