What's the difference between degrees and radians?
Degrees and radians are two ways to measure angles. Degrees use a 360° circle, while radians use 2π for a full circle. Most calculators can work in either mode.

Frequently Asked Questions
How do I calculate logarithms?
Use 'log' for base-10 logarithms and 'ln' for natural logarithms (base e). For example, log(100) = 2 and ln(e) = 1.
What are the mathematical constants available?
π (pi) ≈ 3.14159 and e (Euler's number) ≈ 2.71828 are available as constants for use in calculations.
Can I use this calculator for complex equations?
Yes, you can combine multiple functions and operations. For example: sin(30) + cos(60) or log(100) × √16.
