Closed form Memes

The top panel shows a simple expression cos(π/7) with the stick figure confidently declaring "He will never have a closed form solution" - a mathematical flex about this innocent-looking angle. Then BAM! The bottom panel hits with an absolutely horrific closed-form expression that's the mathematical equivalent of summoning an eldritch horror. Our poor stick figure is literally spitting out his cereal in shock. This is the mathematical version of saying "that's impossible" right before someone does the impossible. Turns out cos(π/7) does have an exact solution—it's just the stuff of nightmares involving nested radicals and complex numbers. Even calculators need therapy after computing this.
