Phase shift Memes

The ultimate math gang rivalry! This meme brilliantly parodies street gang culture with two mathematicians repping their preferred trigonometric function. The red side argues that cosine is the fundamental function (with sine just being cosine shifted by π/2 radians), while the blue side insists sine is primary (and cosine is just sine shifted). What makes this extra nerdy is that both sides are technically correct! In the world of differential equations, you can derive either function from the other. It's the mathematical equivalent of the chicken-or-egg debate, but with way more Greek letters. Next time your calc professor asks which is more fundamental, throw up the appropriate gang sign!
