College Algebra by David Cohen


College Algebra by David Cohen

David Cohen's COLLEGE ALGEBRA, Fifth Edition, focuses on teaching mathematics, using a graphical perspective throughout to provide a visual understanding of college algebra. The author is known for his clear writing style and the numerous quality exercises and applications he includes in his respected texts. In this new edition, graphs, visualization of data, and functions are now introduced much earlier and receive greater emphasis. Many sections now contain more examples and exercises involving applications and real-life data. While this edition takes the existence of the graphing calculator for granted, the material is arranged so that one can teach the course with as much or as little graphing utility work as he/she wishes.


1. FUNDAMENTALS. Sets of Real Numbers. Absolute Value. Solving Equations (Review and Preview). Rectangular Coordinates, Visualizing Data. Graphs and Graphing Utilities. Equations of Lines. Symmetry and Graphs, Circles. 2. EQUATIONS AND INEQUALITIES. Quadratic Equations: Theory and Examples. Other Types of Equations. Applied Problems (A Warm-up). Applications. Inequalities. More on Inequalities. 3. FUNCTIONS. The Definition of a Function. The Graph of a Function. Shapes of Graphs, Average Rate of Change. Techniques in Graphing. Methods of Combining Functions, Iteration.

A great way to introduce kids to great books, authors & genres. Parents can find age-appropriate books to share with their children.

Judi Davies – Aberdare Girls Sch

This company is amazing; not only is it is a great opportunity to get books and review them but everyone is so friendly and supportive!

Jemma Rubens, age 10

It gives me a chance to read types of books that I would not normally try, and it motivates me to read every night to finish it!

Alice Horncastle, age 14

I think Lovereading4kids is an amazing company because of the friendly staff and the fabulous chance to read great books before publication.

Adam Graham

I am so pleased to have signed my kids up as they are reading a much wider range of books and even choosing books out of their comfort zone.

Angela East

I love finding new books to read. My mummy and me look at the new ones coming out. I have written reviews of some of them!

Jessica Cobbin – age 7

It’s really exciting to read and review new books, thrilling to see my reviews online and I love finding the final published copies on sale.

Sam Harper – age 10

You give me age appropriate ideas of books I can read and buy for the children and find out what other children their age think of them too.
