Excellent 3rd semester calc
In the inimitable Protter-Morrey style, an excellent treatment of 3rd semester calculus, with partial derivatives, multiple integrals, vector fields and Green's and Stokes' Theorem. Many of the chapters after the introductory ones are stand-alone and can be included or not at the discretion of the instructor. Rigorous and complete. An excellent resource for a serious course in Calc III.
