Problem-solving strategies for convergence in real analysis
59 charsno explicit “when” trigger
Intermediate

Key capabilities

  • Identify sequence and series types
  • Apply ratio and root tests for convergence
  • Verify mathematical inequality bounds
  • Compute series sums for convergent sequences

How it works

It uses a decision tree to categorize series and applies Sympy for limit calculations and Z3 for proving inequality bounds.

Inputs & outputs

You give it
Mathematical series or sequence expression
You get back
Convergence status or computed sum

When to use convergence

  • Test series convergence
  • Verify mathematical bounds
  • Compute series sums

About this skill

Convergence

When to Use

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

Decision Tree

  1. Identify Sequence/Series Type

    • Geometric series: |r| < 1 converges
    • p-series: p > 1 converges
    • Alternating series: check decreasing + limit 0
  2. Apply Convergence Tests

    • Ratio test: sympy_compute.py limit "a_{n+1}/a_n"
    • Root test: sympy_compute.py limit "a_n^(1/n)"
    • Comparison test: find bounding series
  3. Verify Bounds

    • Use z3_solve.py prove for inequality bounds
    • Check monotonicity with derivatives
  4. Compute Sum (if convergent)

    • sympy_compute.py sum "a_n" --var n --from 0 --to oo

Tool Commands

Sympy_Limit

uv run python -m runtime.harness scripts/sympy_compute.py limit "a_n" --var n --at oo

Sympy_Sum

uv run python -m runtime.harness scripts/sympy_compute.py sum "1/n**2" --var n --from 1 --to oo

Z3_Prove

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

Cognitive Tools Reference

See .claude/skills/math-mode/SKILL.md for full tool documentation.

When not to use it

  • When the problem involves non-real analysis domains
  • When the series is divergent and no sum exists

Limitations

  • Limited to real analysis convergence problems

How it compares

This skill provides a programmatic decision tree and automated tool execution compared to manual algebraic derivation.
