PREFACE TO THE INSTRUCTOR This Instructor's Solutions Manual contains the solutions to every exercise in the 12th Edition of THOMAS' CALCULUS by Maurice Weir and Joel Hass, including the Computer Algebra System (CAS) exercises. The corresponding Student's Solutions Manual omits the solutions to the even-numbered exercises as well as the solutions to the CAS exercises (because the CAS command templates would give them all away). ì ì conforms exactly to the methods, procedures and steps presented in the text is mathematically correct includes all of the steps necessary so a typical calculus student can follow the logical argument and algebra includes a graph or figure whenever called for by the exercise, or if needed to help with the explanation is formatted in an appropriate style to aid in its understanding In addition to including the solutions to all of the new exercises in this edition of Thomas, we have carefully revised or rewritten every solution which appeared in previous solutions manuals to ensure that each solution Every CAS exercise is solved in both the MAPLE and an example of the CAS commands needed to execute the solution is provided for each exercise type. Similar exercises within the text grouping require a change only in the input function or other numerical input parameters associated with the problem (such as the interval endpoints or the number of iterations).
