Can we solve the functions describing the bend of a cable at rest fixed at two positions?
Assume we have a cable which endpoints is attached to two points at $(x,h)$ and $(x+\Delta_x,h)$.
Further assume it has some mass density distribution, $\rho(m),m \in [0,l]$ and is of some length $l ...

In optimization, what is the point of finding argmax of a probability density function?
For example, I am given a line fitting problem
Find pair $(a,b)$ that best fits $y_i = ax_i + b + z_i$, where $z_i$ is iid gaussian noise
Why would we try to find:
$(a^*, b^*)$ = argmax $\ p_{x,y}(...
