Looking at point.hpp, can someone please tell me what do the following
functions do?
norm(point p);
arg(point p);
I know norm() is multiply all components of a point by itself and adding the
result, but what does it physically mean?
I recall from my school days that, for example, if we have a triangle with one
side 3 units and the other side 4 units, then the length of the third side was:
sqrt(3*3 + 4*4)
Can someone please give me a similar explanation for norm and arg.
