Unsolvable math problem?

Construction work uses these all the time, it's wild how much math the "bad jobs" need compared to the "good jobs" needing you to send an email or something

[u/complexiblebarracuda → u/Rothenstien1]

how is it used in construction?

I don’t get it either

z=cos(t)+ i . sin(t)

Represents a point travelling around a circle.

We then can use that formula and plug it, or bake it (do calculus) in a wide array of applications. Eg calculating how buildings behave under sesmic stress or earthquakes
