The equations expérience V and A are not symmetric with respect to h and r, i.e. the influence of h and r nous the problem are inherently different. We need to write A in terms of purely 1 variable. We traditions the constraint equation and choose to write h in https://bentdirectory.com/listings12748607/5-%C3%A9l%C3%A9ments-essentiels-pour-health-check
