Description Unit circle – T-Shirt und Hoodie mit Einheitskreis für Mathe-Fans

Normally, our T-shirts are aimed more at people who have already discovered their love of mathematics and the rest of the natural sciences. But as a true nerd store, we are of course also committed to our educational mission and want to introduce as many people as possible to the wonderful world of mathematics who have had little to do with formulas and the like.

For this reason, we have created the unit circle T-shirt, which, in addition to the unit circle that gives it its name, also shows a transformed version of Euler's identity. Math experts can enjoy the sheer perfection of the unit circle, while newcomers can now wear a useful cheat sheet on their bodies to remind them of the basic principles of trigonometry. Two birds with one stone! ;)
