Scientific Calculator

Advanced online tool for complex mathematical operations

How to Use

  • Basic Operations: Use +, −, ×, ÷ for arithmetic
  • Parentheses: Use ( ) to group expressions
  • Exponents: Use ^ for power (e.g., 2^3 = 8)
  • Percentage: Use % to calculate percentages
  • Constants: π (pi) and e (Euler's number) available

Scientific Functions

sqrt(x) – Square root
sin(x) – Sine (radians)
cos(x) – Cosine (radians)
tan(x) – Tangent (radians)
log(x) – Base-10 logarithm
ln(x) – Natural logarithm
abs(x) – Absolute value
x^y – Power function

Trigonometric functions use radians. Convert degrees: deg * π/180.
