[Verse 1] Calculating limits, it's the calculus game, Approaching the edge, never quite the same. Direct substitution, start with that, If it works out clean, that's where it's at. [Chorus] Limits, limits, finding the line, Approach from both sides, let's see what we find! Direct, squeeze, or L'Hôpital's tool, Get those values, play it cool! [Verse 2] If direct substitution just won't compute, Try the Factor and Cancel route, no dispute. Polynomials, they love to play, Factor them out, simplify the way. [Verse 3] Next up, the Squeeze Theorem, for bounds so tight, Sandwich your function, make sure it's right. When the bounds meet, and the middle’s caught, The limit's captured, not a second thought. [Verse 4] When functions clash, L'Hôpital's Rule steps in, Derivatives fight, let the limit begin. Numerator, denominator, both must flow, Differentiable paths, that's how it goes.
