    Inequalities hard

    Find the maximum and minimum values of the expression P=\frac{a-b}{c} +\frac{b-c}{a} +\frac{c-a}{b}. Where a,b,c are positive real numbers satisfying the condition min\left \{ a,b,c \right \}\geq \frac{1}{4}max\left \{ a,b,c \right \}

    Hey leezangqe.

    What class is this in? Is this in multi-variable calculus or in an optimization course? Have you learned Lagrange Multipliers?
