cos(0°)=1 · cos(30°)=0.866 · cos(60°)=0.5 · cos(90°)=0
tan(45°)=1 · tan(60°)=1.732
💡 Our scientific calculator works in degrees, not radians. If your problem uses radians, convert first: 1 radian = 180° ÷ π ≈ 57.296°
Keyboard Shortcuts
Power users can operate the scientific calculator entirely from the keyboard:
- Numbers: 0–9 and decimal point
- Operators: + − * / for arithmetic
- Enter or = for equals
- Backspace to delete last digit
- Escape to clear all
Frequently Asked Questions
Yes, our scientific calculator defaults to degree mode for standard trigonometric inputs. Make sure to convert values if your equations require radians.
Absolutely. The calculator has dedicated buttons for inverse trig functions like arcsin (asin), arccos (acos), and arctan (atan) to find angles easily.
We have pre-programmed high-precision values for Pi (π), Euler's number (e), and Tau (τ) to guarantee accuracy in mathematical calculations.
