By Marvin L. Bittinger
The Graphs and Models sequence by means of Bittinger, Beecher, Ellenbogen, and Penna is understood for aiding scholars “see the maths” via its concentrate on visualization and know-how. those books proceed to take care of the good points that experience helped scholars prevail for years: specialize in features, visible emphasis, side-by-side algebraic and graphical suggestions, and real-data applications.
With the Fifth Edition, visualization is taken to a brand new point with expertise, and scholars locate extra ongoing review. moreover, ongoing overview has been extra with new Mid-Chapter combined Review workout units and new Study advisor summaries to aid scholars organize for checks.
