... −ε 1  ≥ 0, P 1 (t) −ε 1 > 0, (1.25) for values t ∈ [0,π/2]. Hence, for t ∈ [0,π/2] it is true that g(t) >0 and therefore f (sint)≥ 0fort ∈[0,π/2]. Finally f (x) ≥ 0forx ∈ [0,1].  Remark 1.11. The ... While proving these theorems we use a method for inequalities of the form f (x) ≥ 0, for the continuous function f :[a,b] → R. 1.1. Let us consider some inequalities for the gam...
