pip install simple-equ

Common errors

error ModuleNotFoundError: No module named 'simple_equ' ↓

cause Incorrect import casing (Simple_equ vs simple_equ) or missing install.

fix

Install the library: pip install simple-equ, then import as: from simple_equ import ...

error ImportError: cannot import name 'Arithmetic' from 'simple_equ' (unknown location) ↓

cause Old version (pre-1.0) had different module structure or the library is not installed correctly.

fix

Upgrade: pip install --upgrade simple-equ, or check installed version with pip show simple-equ.

error ValueError: math domain error ↓

cause Passing invalid input to trigonometric functions (e.g., large angles) or sqrt with negative number.

fix

Ensure inputs are within valid domain (e.g., angles in degrees between -360 and 360 for typical use).

Warnings

gotcha The library uses underscores in module names (simple_equ), not hyphens. Import as 'from simple_equ import ...'. ↓

fix Use correct import: from simple_equ import ...

gotcha Some functions expect specific argument order or return values. Always check the docstrings or source code for method signatures. ↓

fix Refer to official documentation for each module's API.

Quickstart

Import and use the core modules: Arithmetic, Trigonometric, Quadratic, Factorial, Kinematics.

from simple_equ import Arithmetic, Trigonometric, Quadratic, Factorial, Kinematics

# Arithmetic
print(Arithmetic.inverse('add'))  # Output: 'subtract'

# Trigonometric
degrees = 30
rad, sin_val, cos_val, tan_val = Trigonometric.evaluate(degrees)
print(f"Radians: {rad}, sin: {sin_val:.2f}, cos: {cos_val:.2f}, tan: {tan_val:.2f}")

# Quadratic
roots = Quadratic.solve(1, -3, 2)
print(f"Roots: {roots}")

# Factorial
print(Factorial.compute(5))  # 120

# Kinematics
time = Kinematics.distance_freefall(10, 9.8)
print(f"Time to fall 10m: {time:.2f}s")
