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
