This is mathematical genius at its finest! The meme cleverly transforms the Swedish flag into a visual representation of the tangent function (tan = sin/cos). The yellow cross perfectly mimics the graph of tangent, with its characteristic vertical asymptotes and that distinctive 90-degree turn.
It's playing on the religious phrase "Jesus died for our sins" but with a mathematical twist - "sin on a cos" (sine divided by cosine). The result? A tangent function that looks exactly like Sweden's flag! Math nerds everywhere are quietly chuckling at their desks right now.
