Continuity

When to Use

Use this skill when working on continuity problems in real analysis.

Decision Tree

  1. Check Definition

    • f(a) exists (function defined at point)
    • lim_{x->a} f(x) exists
    • lim_{x->a} f(x) = f(a)

  2. Use SymPy for Limit Check

    • sympy_compute.py limit "f(x)" --var x --at a
    • Compare with f(a)

  3. Piecewise Functions

    • Check left and right limits separately
    • sympy_compute.py limit "f(x)" --var x --at a --dir left

  4. Verify with Z3

    • z3_solve.py prove "limit_exists implies continuous"

Tool Commands

Sympy_Limit

uv run python -m runtime.harness scripts/sympy_compute.py limit "f(x)" --var x --at a

Sympy_Limit_Left

uv run python -m runtime.harness scripts/sympy_compute.py limit "f(x)" --var x --at a --dir left

Z3_Prove

uv run python -m runtime.harness scripts/z3_solve.py prove "continuous_at_a"
