Tip: Use ^ for powers (2^10), ! for factorial (5!), π for pi, e for Euler's number
Frequently Asked Questions
What functions does this calculator support?
Trigonometry: sin, cos, tan, asin, acos, atan. Logarithms: log (base 10), ln (natural log). Roots: sqrt (square root), cbrt (cube root). Constants: π (pi = 3.14159...), e (Euler's number = 2.71828). Powers: ^ operator. Factorial: ! operator.
How do I calculate sin(30°)?
This calculator uses radians by default (standard for scientific work). To convert degrees to radians: multiply by π/180. So sin(30°) = sin(30 × π/180) = sin(0.5236) = 0.5. Alternatively: sin(π/6) = 0.5.
What is the difference between log and ln?
log is base-10 logarithm (common log). log(100) = 2 because 10² = 100. ln is the natural logarithm (base e). ln(e) = 1. ln is used extensively in calculus, physics, and finance. log is used in pH, decibels, and Richter scale calculations.
How do I calculate exponents?
Use the ^ operator. Example: 2^10 = 1024. For square roots, use sqrt(). For any root: use fractional exponents — cube root of 8 = 8^(1/3) = 2.
