Expression Calculator
calculateRead-onlyIdempotent
Evaluate mathematical expressions from simple arithmetic to trigonometry and logarithms, with variable substitution for dynamic calculations.
Instructions
Evaluate mathematical expressions using SymPy.
Supports: - Arithmetic: +, -, *, /, ^ - Trigonometry: sin, cos, tan, asin, acos, atan - Logarithms: log, ln, exp - Constants: pi, e - Functions: sqrt, abs
Examples:
SIMPLE ARITHMETIC: expression="2 + 2" Result: 4
TRIGONOMETRY: expression="sin(pi/2)" Result: 1.0
WITH VARIABLES: expression="x^2 + 2*x + 1", variables={"x": 3} Result: 16
MULTIPLE VARIABLES: expression="x^2 + y^2", variables={"x": 3, "y": 4} Result: 25
