Finding the complete "old version" (often the 1967 first edition or 1975/1988 printings) solutions for Tom Apostol’s Calculus Volumes 1 and 2
Apostol’s Calculus is not a standard college calculus text. It is a rigorous, proof-heavy introduction to analysis disguised as a calculus book (Volume 1) followed by multivariable calculus and linear algebra (Volume 2). The "old version" (pre-1980s) has distinct exercise sets, notation, and numbering compared to the newer "2nd Edition" (2007 reprint). solucionario calculo tom apostol vol 1 y 2l old version
