I Love Maths T-Shirt
I Love Maths T-Shirt: Take the square-root of minus one: that's "i". The plot y=1/x (looks a bit like an "L"). Next plot all the points where x² + y² = 9 (you basically get a big "O"). y=|2x| is easy, positive values for y with a slope of 2 creating a "V". I think you can see where we're going here... (note to pedants, for the "E" we have halved the scale of the y axis to elongate the letter). Anyway, we love maths.
