Mathematical Analysis. Differential Calculus.

DESPRE CARTE:

Scrisa intr-un limbaj elevat, dar pe deplin accesibila, presarata cu sute de exemple care lamuresc materialul teoretic al acestei discipline fundamentale, raspunzand si cerintelor actuale ale invatarii prin exemple, cartea se constituie intr-un instrument deosebit de util pentru studentii unei universitati de prestigiu.

Referent stiintific - Prof.dr. Pasc Gavruta

Materialul tratat inglobeaza armonios si logic aspectele diferentiale ale analizei matematice, iar multitudinea de probleme rezolvate ori propuse spre rezolvare fac deschiderea catre aplicatiile practice ale analizei.

Este o lucrare reusita, atat din punct de vedere pedagogic, cat si din punct de vedere stiintific, imbinand astfel criteriile utilitatii si eficientei.
