The mathematical walk of shame! This meme shows what happens when you're too lazy to write out the full Taylor series for sine. With each panel, Homer disappears further into the bushes as more terms get dropped from the expansion. For small angles, sin(x) ≈ x is actually a decent approximation, which is why engineers can get away with it. But mathematicians? They'd rather die than commit such blasphemy. The more terms you drop, the more your professor's respect for you vanishes—just like Homer into those bushes.
