"Analytic-Phi" for Math Nerds Trucker Hat
Geometry is one of the most ancient branches of mathematics. The Greeks developed a new method called Co-ordinate geometry or Analytical geometry; which today is also called “Cartesian” after the name of Rene Decartes (1596-1665). In order to transform from rectangular Cartesian coordinates (x,y,z) to spherical ones, and back, use the following Algebraic formulas: x = rho cos(theta)sin(phi), y = rho sin(theta)sin(phi), z = rho cos(phi), rho = ±sqrt(x2+y2+z2), theta = arctan(y/x), phi = arccos(z/sqrt[x2+y2+z2]). The value of phi is usually chosen in the interval between 0 and Pi, inclusive. The sign of rho is determined by which of the values of the arctangent function is chosen. Head hurt yet?? LOL! You must not be a math nerd!!

really cheap for such high durable long lasting quality using different color inks. I think its because they mass produce for a lot of customers is why how they can deliver good lasting quality that is environmental friendly without compromising durability. was great. but light colors or light color letters on dark background has not been best looking unless if its white on black and not light blue on black.

The hat came out awesome . I had a test run done of my clubs logo just to see how it would look. And it came out better than expected. We will be using this company moving forward. Thanks. Excellent hat and printing was above what i was expecting.
