About
limC is a limit calculator that tries to feel like a calculator first and a math tool second: a keypad for entering expressions the way you'd write them by hand, smart parsing that fills in implied multiplication and matches brackets, and a Flask backend that hands the expression to SymPy for a real symbolic evaluation rather than a numeric approximation. Past calculations are kept in a session history so a limit can be revisited without retyping it, and the whole thing installs as a PWA for quick access from a home screen.
The work
The math keypad and result view.
Session history of past calculations.
Started as a way to stop re-deriving the same limits by hand, then grew a
keypad, a parser, and a history because typing lim into a search bar got
old fast.
