About Mathematical Expressions

Mathematical expressions are combinations of numbers, variables, operators, functions, and parentheses that represent mathematical calculations or relationships.

Supported Operations
  • Basic Arithmetic: + (addition), - (subtraction), * (multiplication), / (division), ^ (exponentiation)
  • Functions: sin(), cos(), tan(), sqrt(), log(), ln(), abs(), exp()
  • Constants: pi, e
  • Variables: Any letter can be used as a variable (e.g., x, y, z)
  • Parentheses: Use () to group expressions and control the order of operations
Example Expressions
  • Linear Equation: 2x + 3y = 10
  • Quadratic Expression: x^2 + 5x + 6
  • Trigonometric Function: sin(x) + cos(y)
  • Exponential Growth: A * e^(k*t)
  • Area of Circle: pi * r^2
