Essential Precalculus Formulas and Concepts
This section lays out the foundational elements of precalculus, providing a concise summary of key formulas and concepts crucial for success.
1. Functions and Their Properties
Definition: A function is a relation where each input (x-value) corresponds to exactly one output (y-value).
Domain: The set of all possible input values (x-values).
Range: The set of all possible output values (y-values).
Function Notation: f(x) represents the output of the function f for a given input x.
Types of Functions: Linear, quadratic, polynomial, rational, exponential, logarithmic, trigonometric. Understanding the properties and graphs of each is crucial.
2. Graphing Functions and Transformations
Key Features of Graphs: Intercepts (x and y), asymptotes, maxima/minima, increasing/decreasing intervals.
Transformations: Understanding how shifts (vertical and horizontal), stretches/compressions (vertical and horizontal), and reflections affect the graph of a function is vital. Remember the order of operations for transformations!
3. Solving Equations and Inequalities
Linear Equations: Solve for the unknown variable using basic algebraic operations.
Quadratic Equations: Solve using factoring, the quadratic formula, or completing the square.
Inequalities: Remember to reverse the inequality sign when multiplying or dividing by a negative number. Graphing inequalities on a number line is essential.
4. Systems of Equations
Solving Methods: Substitution, elimination, graphing. Understanding when each method is most efficient is key.
Applications: Systems of equations are frequently used to model real-world problems.
Trigonometry: A Quick Recap
Trigonometry forms a significant portion of precalculus. This section provides a condensed summary of key trigonometric functions, identities, and their graphs.
1. Trigonometric Functions
Definitions: Sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), cotangent (cot). Understanding their definitions in terms of right triangles and the unit circle is fundamental.
Unit Circle: Mastering the unit circle is essential for understanding the values of trigonometric functions at key angles.
2. Trigonometric Identities
Pythagorean Identities: sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, 1 + cot²θ = csc²θ.
Sum and Difference Formulas: These are crucial for simplifying and solving trigonometric equations.
Double and Half-Angle Formulas: Useful for simplifying expressions and solving more complex problems.
3. Graphing Trigonometric Functions
Periodicity: Understand the periodic nature of trigonometric functions and their periods.
Amplitude: The amplitude represents the vertical stretch or compression of the graph.
Phase Shift: A horizontal shift of the graph.
Limits and Continuity: A Glimpse into Calculus
Precalculus provides the foundation for calculus. Understanding limits and continuity is crucial for a smooth transition.
1. Limits
Definition: The limit of a function as x approaches a certain value represents the value the function approaches as x gets closer to that value.
Evaluating Limits: Use algebraic techniques, such as factoring and simplifying, to evaluate limits.
One-sided Limits: Understanding left-hand and right-hand limits is important for determining the existence of a limit.
2. Continuity
Definition: A function is continuous at a point if the limit of the function at that point exists and is equal to the function's value at that point.
Types of Discontinuities: Removable, jump, infinite.

| pre calculus cheat sheet: Linear Algebra Done Right Sheldon Axler, 1997-07-18 This text for a second course in linear algebra, aimed at math majors and graduates, adopts a novel approach by banishing determinants to the end of the book and focusing on understanding the structure of linear operators on vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. For example, the book presents - without having defined determinants - a clean proof that every linear operator on a finite-dimensional complex vector space has an eigenvalue. The book starts by discussing vector spaces, linear independence, span, basics, and dimension. Students are introduced to inner-product spaces in the first half of the book and shortly thereafter to the finite- dimensional spectral theorem. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. This second edition features new chapters on diagonal matrices, on linear functionals and adjoints, and on the spectral theorem; some sections, such as those on self-adjoint and normal operators, have been entirely rewritten; and hundreds of minor improvements have been made throughout the text. |

| pre calculus cheat sheet: Advanced Calculus (Revised Edition) Lynn Harold Loomis, Shlomo Zvi Sternberg, 2014-02-26 An authorised reissue of the long out of print classic textbook, Advanced Calculus by the late Dr Lynn Loomis and Dr Shlomo Sternberg both of Harvard University has been a revered but hard to find textbook for the advanced calculus course for decades.This book is based on an honors course in advanced calculus that the authors gave in the 1960's. The foundational material, presented in the unstarred sections of Chapters 1 through 11, was normally covered, but different applications of this basic material were stressed from year to year, and the book therefore contains more material than was covered in any one year. It can accordingly be used (with omissions) as a text for a year's course in advanced calculus, or as a text for a three-semester introduction to analysis.The prerequisites are a good grounding in the calculus of one variable from a mathematically rigorous point of view, together with some acquaintance with linear algebra. The reader should be familiar with limit and continuity type arguments and have a certain amount of mathematical sophistication. As possible introductory texts, we mention Differential and Integral Calculus by R Courant, Calculus by T Apostol, Calculus by M Spivak, and Pure Mathematics by G Hardy. The reader should also have some experience with partial derivatives.In overall plan the book divides roughly into a first half which develops the calculus (principally the differential calculus) in the setting of normed vector spaces, and a second half which deals with the calculus of differentiable manifolds. |

| pre calculus cheat sheet: Analysis I Terence Tao, 2016-08-29 This is part one of a two-volume book on real analysis and is intended for senior undergraduate students of mathematics who have already been exposed to calculus. The emphasis is on rigour and foundations of analysis. Beginning with the construction of the number systems and set theory, the book discusses the basics of analysis (limits, series, continuity, differentiation, Riemann integration), through to power series, several variable calculus and Fourier analysis, and then finally the Lebesgue integral. These are almost entirely set in the concrete setting of the real line and Euclidean spaces, although there is some material on abstract metric and topological spaces. The book also has appendices on mathematical logic and the decimal system. The entire text (omitting some less central topics) can be taught in two quarters of 25–30 lectures each. The course material is deeply intertwined with the exercises, as it is intended that the student actively learn the material (and practice thinking and writing rigorously) by proving several of the key results in the theory. |
