Unreleased

0.6.1 - 2025-01-30

  • Do not set -Werror by default in preparation for upload to Hackage.

0.6.0 - 2025-01-29

  • For rational function integration, use complex logarithms if we are not able to derive real function integrals.

  • Add function to map polynomial coefficients monadically.

0.5.0 - 2025-01-20

  • Implement integration by parts.

  • Attempt integration by substitution after factoring out constant factors.

  • Prefer positive integers in fraction denominators.

  • Cancel out common integer fractions in \(\frac{1}{x} \times y\) as well.

0.4.0 - 2025-01-14

  • Integrate more rational functions.

    • Find all real roots for integration involving solution of cubic equations.

    • For integration involving solution of quartic equations, find real roots for more special cases.

  • Cancel out common integer factors in fractions.

  • Fewer parentheses in Haskell code output.

  • Fewer parentheses in LaTeX output.

  • Test with GHC 9.12.1.

0.3.0 - 2025-01-05

  • Implementation of Rioboo's algorithm.

    • Supports integration of more rational functions.

    • Integration of rational functions with rational number coefficients now only limited by finding solutions for polynomials. As of yet, only rational functions which require solutions for polymials up to degree 2 can be integrated.

  • Output pi as \pi in LaTeX.

0.2.0 - 2025-01-02

  • Integration of rational functions.

    • Hermite reduction.

    • Lazard-Rioboo-Trager integration.

  • Improvements to LaTeX output.

  • Remove simplification based on recursive heuristics, which were much more ad hoc.

  • Make foldTerms order consistent with simplification order, from lower to higher terms.

0.1.0 - 2024-12-24

  • Symbolic representation.

  • Simplification.

  • Basic integration support.

    • Integration of polynomials.

    • Integration of trigonometric functions.

    • Integration of exponential and logarithmic functions.

    • Integration by substitution.
