formula-math

I made this cause I always struggled with keeping up with formulas and remembering each one.

This is a beginner-friendly Python library for math, finance, geometry, trigonometry, statistics, physics, and original helpers. No need to memorize formulas — just call the function with your values and get results instantly.

Installation

pip install formula-math
