X-y plane Memes

The equation x² - y² = 1 isn't just any curve—it's a hyperbola, not a "diagonal rational function." Math professors everywhere are collectively facepalming. The joke hinges on the fact that if you tilt your head (or screen) 45 degrees, the hyperbola looks like an X... hence the "hey guys, not what I'm called" quip. It's basically the mathematical equivalent of a dad joke where the hyperbola is saying "I'm not an X, despite looking like one from a certain angle." Mathematicians spend years studying these curves only for students to reduce them to alphabet lookalikes. Pure geometrical identity crisis.
