Usage

Important: All inputs must use LaTeX format!

bash

python3 <skill-path>/scripts/calc.py "<LaTeX expression>" [language]

LaTeX Format Guide

• Multiplication: Use \times or \cdot, e.g., 3 \times 4
• Division: Use \div or /, e.g., 8 \div 2
• Fraction: Use \frac{numerator}{denominator}, e.g., \frac{1}{2}
• Square root: Use \sqfrt{number}, e.g., \sqrt{16}
• Power: Use ^, e.g., x^2
• Trigonometric functions: \sin, \cos, \tan, etc.
• Inequality symbols: \geq, \leq, >, <
• Greek letters: \pi, \theta, \alpha, etc.
• System of equations: Use \begin{cases}...\end{cases}, e.g.:

  text

  \begin{cases}
  x + y = 10 \\
  x - y = 2
  \end{cases}
  

Core Features

1. Basic Operations

• Arithmetic operations: +, -, \times, \div
• Power operations: x^2, x^3
• Roots: \sqrt{x}, \sqrt[3]{x}
• Fractions: \frac{a}{b}
• Percentage calculations

2. Scientific Calculations

• Trigonometric functions: \sin(x), \cos(x), \tan(x), \arcsin(x), \arccos(x), \arctan(x)
• Logarithms: \log(x), \ln(x), \log_{a}(b)
• Exponentials: e^x, a^b
• Others: Absolute value |x|, factorial n!
• Constants: \pi, e

3. Equation Solving

Supports solving various algebraic equations (no need for solve() wrapper):

• Linear equations: 2x + 5 = 15
• Quadratic equations: x^2 - 5x + 6 = 0
• Higher-order equations: x^3 - 6x^2 + 11x - 6 = 0
• System of linear equations (two variables):

  text

  \begin{cases}
  x + y = 10 \\
  x - y = 2
  \end{cases}
  

• Multi-variable systems:

  text

  \begin{cases}
  x + y + z = 6 \\
  2x - y + z = 3 \\
  x + 2y - z = 2
  \end{cases}
  

4. Inequality Solving

Supports solving various inequalities (no need for solve() wrapper):

• Single-variable inequalities: 2x + 5 > 15
• Quadratic inequalities: x^2 - 4 \geq 0
• Inequality systems: x + 2 > 5, x - 3 < 10

5. Step-by-Step Solutions

Automatically returns detailed calculation process, for example:

text

Input: x^2 - 5x + 6 = 0
Step 1: Identified as a quadratic equation
Step 2: Using factorization method (x-2)(x-3) = 0
Step 3: Solutions found: x = 2 or x = 3
Result: x = 2, x = 3
