Precalculus Mathematics For Calculus 7th Edition Answers

[Algernon Alcala]

Precalculus is a course that covers algebra, trigonometry, and other fundamental mathematical concepts that are necessary for understanding calculus. Calculus is a branch of mathematics that deals with the study of change and motion, and involves concepts such as derivatives and integrals.

"Precalculus Mathematics in a Nutshell" is a reference book that provides a concise summary of important precalculus concepts. It is designed to help students review and reinforce their understanding of precalculus before moving on to calculus.

Spivak's Calculus is considered a classic textbook because it presents calculus in a rigorous and comprehensive manner, while also being accessible to students with a strong mathematical background. It provides clear explanations and challenging exercises that help students develop a deep understanding of the subject.

Yes, knowledge of precalculus is essential for learning calculus. Many of the concepts and techniques in calculus build upon those learned in precalculus. Without a strong foundation in precalculus, students may struggle to understand and apply the concepts in calculus.

"Precalculus Mathematics in a Nutshell" can be used as a review and reference guide for students studying Spivak's Calculus. It provides a quick overview of important precalculus concepts, while Spivak's Calculus offers a more in-depth exploration of calculus. Together, these resources can help students develop a strong understanding of both precalculus and calculus.

I was reading an online article and the author mentioned I should come here and get some advice. I'm 17, currently taking Pre-Calc in high schooling doing really good, but I feel like I'm not getting the most out of it. The teacher feels like he's more interested in covering chapters than getting us to understand things deeply and that worries me. The article says:

Try to find a book where the author treats you as the intelligent, independent person you are, not as someone who has to take a course for a degree requirement...go to some math forums (like Math Overflow) and ask for book recommendations, telling them you want to become good at math and not just pass a required course; give them specific details and they can help find a book perfect for you.

So yeah asked on Math Overflow and was suggested to come here. I want to get better at math and really understand the concepts deeply and appreciate it like it was intended to. Any help I can get will be appreciated. Thanks!

The series of books Algebra, Functions and Graphs, Trigonometry, and The Method of Coordinates by I. M. Gelfand and various co-authors is an excellent way to supplement a pre-calculus course. The books were written for advanced high school students taking correspondence courses with professors in the Soviet Union and are available in English translation. The books are clearly written, supplement topics found in the typical pre-calculus text, and provide challenging problems.

Another good source is a series of Japanese books edited by Kunihiko Kodaira. They include Mathematics I: Japanese Grade 10, Basic Analysis: Japanese Grade 11, and Algebra and Geometry: Japanese Grade 11. These books are also available in English translation. The grade 10 book is for a required course roughly equivalent to pre-calculus. Regular track students then take a course based on Mathematics II: Japanese grade 11. Mathematically inclined students take courses based on both the Algebra and Geometry and Basic Analysis texts. The texts are a good source of challenging problems and contain material that will supplement what you would learn in a pre-calculus course.

I'm considerably older than you and failed miserably at math in high school so this may not apply to your case, but I found "Precalculus Mathematics in a Nutshell" by George F. Simmons to be a fantastic encapsulation of pre-calc topics when studying math as an adult. He really boils it down to the essentials. E.g. here's how he opens his chapter on Trig:

Most trigonometry textbooks have been written by people who appear to believe that the importance of the subject lies in its applications to surveying and navigation. Even though very few people become surveyors or navigators, the students who study these books are expected to undertake many lengthy calculations about the heights of flagpoles, the widths of rivers and the positions of ships at sea.

The truth is that the primary importance of trigonometry lies in a completely different direction - in the mathematical description of vibrations, rotations, and periodic phenomena of all kinds, including light, sound, alternating currents and the orbits of the planets around the sun. What matters most in the subject is not making computations about triangles, but grasping the trigonometric functions as indispensable tools in science, engineering and higher mathematics. These functions and their properties are the sole subject matter of this chapter.

I can recommend the Precalculus volume of a series called the CME Project. It's a high school textbook written by a team of thoughtful and savvy mathematicians. It works to make connections between topics, emphasizes making use of structure in calculation, and builds generalizations from concrete cases. It's a "habits of mind" approach that focuses on mathematical thinking and not just rote processes. I think you'll find in this book what is lacking from your class. Enjoy!

there is a series of books written by gelfand and shen, i believe, is very nice. in particular used on of their books called algebra. it teaches you mainly through solving lots and lots of problems. i don't have at hand but it has hundreds of problems.

"Pre-calculus" is not a subject that exists for any intellectually legitimate reason. So my suggestion would be either to simply start learning calculus or to explore wider mathematical horizons, for instance, number theory.

For calculus, practically the only modern book that treats the reader as a reader, let alone as an "intelligent, independent person," is Michael Spivak's Calculus. This requires no previous knowledge of the material of precalculus-in fact, Spivak will start much farther back, and you won't even define such functions as $e^x$ and $\sin$ until well into the book (of course, in your current course, these functions were never properly defined at all.) That said, you will almost certainly find his problems an order of magnitude more challenging than what you've seen 'till now, but the solutions manual is readily available, and, of course, so are the members of this site!

I don't have any particularly specific suggestions for number theory, but there are several Dover books with titles like "elementary number theory" with good reviews (stay away from "analytic" or "algebraic" number theory for now.) The great thing about Dover books is you can buy three for half the price of an ordinary book and compare. Best of luck!

Mathematics is both a fundamental discipline and an essential tool for students of biology, chemistry, computer engineering, computer science, Earth sciences, economics, electrical engineering, information systems management, physics, and psychology. Researchers in all these areas are constantly developing new and cutting-edge ways of applying mathematics to their fields. A strong mathematics background is vital to the advanced study of the physical and biological sciences and plays an integral role in studying the social sciences.

Courses 2 and 3 do not require thorough preparation in mathematics at the high school level. However, students interested in studying mathematics are strongly encouraged to take algebra, geometry, and trigonometry before entering the university. Students requiring mathematics courses are encouraged to take the mathematics placement examination (MPE) as early as possible. Students concerned about their ability to place into courses above Mathematics 2 or Mathematics 3 should consider taking these courses before they enter UCSC. Failure to begin the calculus series in the fall could delay progress in some majors.

Lower-division courses with numbers in the range 11A-B through 30 (calculus, linear algebra, multivariable calculus, differential equations, and problem solving) prepare students for further study in mathematics, the physical and biological sciences, or quantitative areas of the social sciences. Science majors take a combination of these courses as part of their undergraduate studies.

Upper-division courses, with numbers in the range 100-199, are intended for majors in mathematics and closely related disciplines. Some of these courses provide students with a solid foundation in key areas of mathematics such as algebra, analysis, geometry, and number theory, whereas others introduce students to more specialized areas of mathematics. Calculus, linear algebra, multivariable calculus, and proof and problem solving are prerequisite to most of these advanced courses.

Within the major, there are three concentrations leading to the bachelor of arts (B.A.) degree: pure mathematics, computational mathematics, and mathematics education. These programs are designed to give students a strong background for graduate study, for work in industry or government, or for teaching. Each concentration requires nine or ten courses, one of which must be a senior thesis or senior seminar. Please read the pure mathematics, computational mathematics, and mathematics education program descriptions below for specific information about course requirements. A minor in mathematics is also offered.

The mathematics program also provides an excellent liberal arts background from which to pursue a variety of career opportunities. UCSC graduates with degrees in mathematics hold teaching posts at all levels, as well as positions in law, government, civil service, insurance, software development, business, banking, actuarial science, forensics, and other professions where skills in logic, numerical analysis, and computing are required. In particular, students of mathematics are trained in the art of problem-solving, a skill absolutely essential to all professions.
