Review # 1 was written on 2019-11-30 00:00:00 Leon Walls I've had my nose in this hefty Stewart tome for years and years. It's served me well but it's outlived its usefulness to me. It's far too numerical and formulaic without giving a treatment to the true analytical theory that underlies the beauty of calculus as a discipline and a science. This is merely "toolkit calculus" and I fear it abstracts engineering and science students away from the underlying theory that mathematicians are treated to. This makes for a decent human calculator. Engineers should be applied mathematicians, not calculators. Alternatives: early editions of Thomas, Apostol, or Spivak.
