Full Description
Axler's College Algebra focuses on depth, not breadth of topics by exploring necessary topics in greater detail. Students will benefit from the straightforward definitions and plentiful examples of complex concepts. The Student Solutions Manual is integrated at the end of every section. The proximity of the solutions encourages students to go back and read the main text as they are working through the problems and exercises. The inclusion of the manual also saves students money.
Axler's College Algebra is available with WileyPLUS; an innovative, research-based, online environment for effective teaching and learning.
