Thinkwell's Precalculus with Edward Burger lays the foundation for success because, unlike a traditional textbook, students actually like using it. Thinkwell works with the learning styles of students who have found that traditional textbooks are not effective. Watch one Thinkwell video lecture and you'll understand why Thinkwell works better.
This is Thinkwell's Precalculus course, and thereby is training for College Algebra Trigonometry.

Tackle the toughest math and science problems with ease
From basic math to precalculus, Microsoft Math helps you visualize and see mathematical concepts as you’ve never seen them before. It gives you step-by-step instruction, while providing you with a better understanding of fundamental concepts.
Microsoft Math includes

Math software designed to solve algebra, geometry, trigonometry, and calculus homework problems with step-by-step help. Includes Algebra 2 Solved!, Algebra Solved!, Calculus Solved!, Geometry Solved!, Graphing Solved!, Precalculus Solved! and Trigonometry Solved! Portable 'Bagatrix Bundle 2008.10.10' does not require installation. Make as many copies as you need. Carry it in a flash drive and use on any computer, even without administrator access. No change of any setting on the host computer. No more conflicts with other applications. No more 'hijacking' of file types. All dependencies are included.

Description : The unique feature of this compact student`s introduction is that it presents concepts in an order that closely follows a standard mathematics curriculum, rather than structure the book along features of the software. As a result, the book provides a brief introduction to those aspects of the Mathematica software program most useful to students. The second edition of this well loved book is completely rewritten for Mathematica 6 including coverage of the new dynamic interface elements, several hundred exercises and a new chapter on programming. This book can be used in a variety of courses, from precalculus to linear algebra. Used as a supplementary text it will aid in bridging the gap between the mathematics in the course and Mathematica. In addition to its course use, this book will serve as an excellent tutorial for those wishing to learn Mathematica and brush up on their mathematics at the same time.

Microsoft Math's large collection of tools, tutorials, and instructions helps students learn mathematical concepts, while quickly solving math and science problems. Students see how to solve problems step-by-step - instantly. Microsoft Math works for many grade levels, studying subjects from basic math to calculus

Geometry Expressions is the first software package that allows you to interact with their numeric and symbolic. This interaction brings together geometry and algebra symbolic, for the first time in an interactive geometry. This interaction brings together geometry and algebra symbolic, for the first time in an interactive geometry.

The benefits of this type of system are:
* Many geometric configurations are much more easily with the constraints specified by construction. Many geometric configurations are much more easily with the constraints specified by construction.
* This is a much more convenient style for expressing real world problems. It is a style much more convenient to express real world problems.
* This is the approach used in modern Computer Aided Design (CAD). This is the approach used in modern Computer Aided Design (CAD).
