Inverse functions Memes

The mathematical equivalent of being told "you ain't seen nothing yet." First, we're shown sine and tangent functions—both continuous and well-behaved. Then comes the punchline: tan⁻¹(tan(x)), which looks like it should simplify to just x, but instead gives us this discontinuous nightmare of parallel lines. It's the mathematical equivalent of your advisor saying "your first experiment was just the warm-up." That function isn't continuous—it's having an existential crisis every π radians. No wonder my pen has been lifted into the stratosphere; I've thrown it there in frustration.
