With the help of this clear, easy-to-use resource, you’ll soon get a handle on all of the concepts — not just the number crunching — and understand how to perform all pre-calc tasks, from graphing to tackling proofs. You’ll also get a new appreciation for how these concepts are used in the real world, and find out that getting a decent grade in precalc isn’t as impossible as you thought. Discover how to:

• Apply the major theorems and formulas
• Understand quadratic, square-root, absolute value, cubic, and cube-root functions
• Graph trig functions like a pro
• Flip-flop with inverse functions
• Find trig values on the unit circle
• Work with trig identities and advanced identities
• Tackle analytic geometry
• Solve oblique triangles with the laws of sines and cosines
• Use polar coordinates to express points on a plane
• Identify function limits and continuity
• Place vectors on a coordinate plane.
• Rotate and shift conic section forms
• Solve systems with mingling and matrices

If “the fun and easy way to learn pre-calc” seems like an oxymoron to you, order Pre-Calculus For Dummies today, and get ready to be surprised!

I translate for engineering students from foreign countries, and I use this book to help me with my limited knowledge of Calculus, pre-Calculus, etc. I find all the "for Dummies" series very helpful.

Good book but not perfect

Customer Rating:

The aim of this book is to introduce the subjects of pre-calculus in an easy, yet complete way. For the most part it accomplish it's objective, nevertheless, it has some typos and errors that will cause the student to get confused (i.e. the first time the student is shown the formula for the difference of cubes the book says something like this (a-b)(a^2+ab+b^3) which is wrong and in latter examples the formula takes the correct form of (a-b)(a^2+ab+b^2) which causes some confusion). Overall, this is a very good book specially for a review of the subjects. UPDATE P.105 Changing a Log's Base log5/log3 does not equal ln3/ln5... it should read log5/log3 = ln5/ln3.
