[Verse 1] L'Hôpital, from Paris town, 16th-century legend, never let us down. Differentiable functions, all around, When limits play tricks, his rule's sound. [Chorus] L'Hôpital's rule, breaking the mold, Use it if you're bold, let the truth unfold! [Verse 2] Functions f and g, on open ground, Derivatives in, no zero nor infinity to be found. Quotient of derivatives, take the lead, Limits revealed, no more mystery to heed.
