Several software options can solve integrals step-by-step, primarily through computer algebra systems that employ different methodologies than traditional human approaches. The Risch Algorithm is commonly used for integrals involving elementary functions. Wolfram Alpha features a "Show Steps" function for many basic math problems, which utilizes pattern recognition and replacement rules, although it does not use these steps in its calculations. Additionally, TK Solver provides the ability to view iterations, but it comes at a higher cost.
