What is the formula for minima?

Could you please explain the formula for minima in simpler terms? I'm having trouble understanding how it's derived and how it's used in various financial and cryptocurrency contexts. I'm specifically interested in how it relates to minimizing risk or optimizing returns in investment strategies. Additionally, are there any specific applications or examples where the formula for minima is particularly useful or important? It would be great if you could provide some real-world scenarios where it's employed to achieve better outcomes.
