Cubic equations Memes

The math gods blessed us with beautiful, elegant formulas for most cosine values... and then there's cos(π/7) with its ridiculous cubic equation solution! This meme is basically the mathematical equivalent of having friends with perfect handwriting while yours looks like a seismograph during an earthquake. The pattern is hilarious - all these nice, clean values for cos(π), cos(π/2), cos(π/3), etc., forming a satisfying "Thank you all for having easy formulas!" And then BAM! Cos(π/7) shows up with that monstrosity involving cubic equations and ruins the party. Mathematicians literally had to create a special case just for this awkward angle! It's like that one friend who can't just order a normal coffee but needs 17 specific modifications.
