# Complex visualization: Euler’s Identity This is just a quick way to practice your ability to visualize in 3D, Euler’s Formula, which relates e^(ix) to the featured image, where basically the unit circle of trigonometric functions becomes a helix as the input into the function itself is mapped so f(x,y) as function of z, and we see how as we increase the Greek argument into the function, what e^(ix) is equal to remains fixed on the unit circle but may be quite popped off the page if we have entered in a high real number for the radian input. The goal of this exercise is to show you the difference between a spiral and a unit circle, and that is a spiral maps the input as well, as a coordinate, and as thus, if you really are in a downward spiral there probably is no way for you to get out except by reversing the input argument, so you must recover in a spiral too.

Pure Mathematics and Literature
Pure mathematics starts as a great model for the mind. There is the concept of axiom of choice, which is dependent on the future, and being able to select subsets out of sets extending into the future. There is the axiom of determinism which states that one can win a game with start parameters if you use the best moves. These two axioms are incompatible. Taken together, these axioms guide...
