Scientific Calculator Features & Supported Functions

This calculator supports all essential scientific operations and advanced calculations.

Trigonometric Functions

  • sin(x), cos(x), tan(x) (x in radians)
  • Use π button for radian-friendly input

Logarithmic & Exponential Functions

  • log(x) → base-10 logarithm
  • ln(x) → natural logarithm (base e)
  • xʸ → exponent function

Root & Factorial

  • √x → square root
  • x! → factorial

Arithmetic

  • Addition, subtraction, multiplication, division
  • Parentheses support

Special Constants

  • π = 3.141592653589793
  • e = 2.718281828459045

Function Formulas

sin(x) = opposite / hypotenuse
cos(x) = adjacent / hypotenuse
tan(x) = sin(x) / cos(x)
log(x) = logarithm base 10
ln(x) = natural log base e
√x = x^(1/2)
xʸ = power function

Input Rules

  • Expressions evaluate in standard math order (PEMDAS).
  • Angles are interpreted in radians.
  • Factorial only works for non-negative integers ≤ 170.
  • log(x) and ln(x) require x > 0.
