Frequently Asked Questions
What mathematical operations are supported?
Our scientific calculator supports basic arithmetic (+, -, ×, ÷), powers (^), square root (√), trigonometric functions (sin, cos, tan), and logarithmic functions (log, ln). You can also use parentheses for grouping and constants like π and e.
How do I switch between radians and degrees?
Use the "Angle Mode" toggle above the input field. In Degrees mode, trigonometric functions automatically convert angles to radians. For example: sin(30) in Degrees mode = 0.5, while sin(30) in Radians mode ≈ -0.988.
How do I use constants like π and e?
You can type "pi" or "e" directly in the expression, or use the constant buttons. The calculator will automatically recognize and convert them to their numerical values.
Can I adjust the precision of results?
Yes! Click the settings icon to adjust decimal precision from 2 to 12 digits. Very large or small numbers will automatically display in scientific notation.
How does the history feature work?
The calculator keeps track of your last 5 calculations. Click the history icon to view and reuse previous expressions and results.
What happens if I enter an invalid expression?
The calculator will display an error message. Make sure your expression uses valid mathematical syntax, proper parentheses pairing, and supported functions.
