Viraly all types of problems ordinarily encountered in study and practice in these areas are covered. Not only you. but teachers, practtinners, and graduates, reviewing ing licensing examinations shoul! find these problems vafuable it you ‘with cur “approach,” partular steps taken in presenting the problems and their solutions axe itemized below + Fist anil ost important of all, eeeh problem amd its sclution are essentially independent ain! selteuntaincd. That is co say, walt contains all the data, equations, and computations every 10 find the sners.
