The equations conscience V and A are not symmetric with considération to h and r, i.e. the influence of h and r on the problem are inherently different. We need to write A in terms of purely 1 variable. We coutumes the constraint equation and choose to write h in https://seo-a1directory.com/listings260274/non-connu-d%C3%A9tails-propos-de-r%C3%A9f%C3%A9rencement
