Description

Supports solving equations like:

  • Simul Equation
    • 2 Unknowns
    • 3 Unknowns
    • 4 Unknowns
    • n Unknowns
  • Polynomial
    • $ax^2 + bx + c$
    • $ax^3 + bx^2 + cx + d$
    • $ax^4 + bx^3 + cx^2 + dx + e$
    • $a_n x^n + a_{n-1}x + a_{n-2}x^{n-2} + \dots + a_1x^1 + a_0$
  • Equation (Find values of variable)

Maybe this feature is not suitable for your library but it would be nice if it was added. I found a similar library for this feature but it seems to be no longer maintained. https://github.com/Samshal/Equation-Solver

Contributor guide

Research direction
Study the existing expression parser structure, then implement numerical methods for solving linear equations (e.g., Gaussian elimination) and polynomial equations (e.g., using roots or factorization).
