  • Aplicarea monotoniei funcţiilor la rezolvarea ecuaţiilor 
    CORLAT, Andrei; JARDAN, Ion (Technical University of Moldova, 2021)
    În procesul rezolvarii ecuatiilor se utilizeaza diferite proprietati ale functiilor elementare: marginirea, periodicitatea, paritatea, monotonia etc. Proprietatea de monotonie se întâlneste mai des, deexemplu, daca se cere ...
  • Some particular cases for inverse operations in the class of preradicals in modules 
    JARDAN, Ion (Technical University of Moldova, 2021)
    Four new operations are introduced and studied in the class of preradicals PR in modules, namely, the inverse operations of the product and of the coproduct with respect to meet and to join.
  • Unele aspecte ale integrării funcţiilor raţionale 
    CORLAT, Andrei; JARDAN, Ion (Technical University of Moldova, 2021)
    La integrarea functiilor rationale se utilizeaza metoda coeficientilor nedeterminati. De regula, se obtine un sistem de n ecuatii liniare (n≥2,nєN), care pentru un numar de coeficienti nedeterminati mai mare ca trei, ...
