I am a high school student who has finished calculus, multivariable calculus, and differential equations, but I feel as though the treatment I received of those topics was rather inadequate and shallow - lacking mathematical rigor, so to speak. Can anyone comment on the quality of those two textbooks for self-study (as well as for teaching other students calculus over the summer)? I would buy Apostol or Spivak, but they are horrendously expensive and probably impractical given my current financial situation.(adsbygoogle = window.adsbygoogle || []).push({});
