This specialization helps to build the foundational material to use mathematics as a tool to model, understand, and interpret the world around us. This is done through studying functions, their properties, and applications to data analysis. Concepts of precalculus provide the set of tools for the learner to begin their scientific career, preparing them for future science and calculus courses.
This specialization is designed for all learners, not just those interested in further mathematics courses. Those interested in the natural sciences, computer sciences, psychology, sociology, or similar will genuinely benefit from this introductory course, applying the skills learned to their discipline to analyze and interpret their subject material.
Learners will be presented with not only new ideas, but also new applications of an old subject. Real-life data, exercise sets, and regular assessments help to motivate and reinforce the content in this course, leading to learning and mastery.
In each module, learners will be provided with solved sample problems that they can use to build their skills and confidence followed by graded quizzes to demonstrate what they've learned. Finally, each course in the specialization concludes with a final exam that learners can use to demonstrate their mastery of the material.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. If you only want to read and view the course content, you can audit the course for free. If you cannot afford the fee, you can apply for financial aidOpens in a new tab.
I'm a software developer looking to make a career switch to Mechanical Engineering (at least I think so). My interests lie in design, complex systems, maglev, rockets, and new forms of space propulsion. Before I really commit myself to University, I would like to get my feet wet in Physics/Engineering. Most likely I'd major in Applied Physics or Engineering Physics.
Ultimately, my goal is to get through Fundamental University Physics by Alonso & Finn and then to get through Shigley's Mechanical Engineering Design. Alonso's text seems to require some heavy duty calculus, and Courant's calculus book seems to have a lot of practical application problems so I think the two would complement one another.
The only problem is, I'm not exactly sure what kind of precalculus prep I would need for that. Principles of Mathematics by Allendoerfer looks to be a rigorous and proof-focused trek through precalculus, but I'm not sure that this would be the best book for me if my preferences lean towards the more practical.
Now, how should I handle this whole precalculus thing? I skimmed through Addison-Wesley's Algebra and Trigonometry and I love that it's replete with practical-looking problems and novel facts about the given subtopic but it feels like a "plug and chug" type book. And as cool as calculating the parabolic cross sections of a car's headlights seems, problems like these feel cheap and trivial.
So what's a good precalculus book for the aspiring Applied Physicist / Engineer? Should I just stick with Principles of Mathematics?. Or should I replace that with Precalculus Mathematics in a Nutshell or Serge Lang's Basic Mathematics? What would best prepare me for Courant's book and beyond, given my goals?
Courant's book has proofs and theory in it, so you should read a better algebra book than Jacobs (except if you've never studied any algebra at all), perhaps Basic Mathematics by Lang as you suggest.
Lang's book will give you enough geometry too, including some discussion of vectors. There's no need to read a whole geometry book. Geometry Revisited is difficult and is not useful for calculus. It covers material that would rarely if ever be needed for physics.
I don't particularly like the book by Allendoerfer (if it's the one I'm thinking of). It's not entirely rigorous. It introduces some advanced concepts, but then studies them very superficially. My recollection is that at times it also accepts some statements without proof but without even mentioning that fact.
The books by Gelfand are a great idea, particularly Algebra and Functions and Graphs. The Method of Coordinates is also good. The trigonometry book is okay but not terrific. It seems to have been written mainly by the American coauthor and is dumbed down compared to Gelfand's trig book in Russian. (The others are actual translations.) Again, Basic Mathematics is likely to be enough here, but if not, you also have other choices, such as Trigonometry by Nobbs (which you can read after the trigonometry sections of Lang).
Another possibility, though not strictly necessary, would be an introduction to vector geometry beyond what's contained in Lang's book. For example, Elementary Vector Algebra by Macbeath. This isn't really important for single-variable calculus, but it's important for physics and for multivariable calculus. You can put this off until later if you like.
One last point I'd make is that one possible consideration when choosing between Courant, Apsotol and Spivak is that Spivak has a complete solution manual. Even if these books differ in some ways, they're more alike than they are different, so the solution manual could make Spivak worth it.
The refresh includes programmatic changes as well. While the focus on precalculus instruction remains the same, the learning methodology will follow findings from the Student Experience Project, a multi-university collaboration with experts in the science of learning and researchers who focus on factors in student success.
Growth mindset is a central theme of the research from the Student Experience Project. With a growth mindset, a student begins to understand that success is a process and that failing or making mistakes is inherent to that process. New communication materials from the Precalculus Center will focus on encouraging a growth mindset for students.
Known as Khanmigo, the program is the product of Khan Academy, an online tutoring company with instructional materials for core middle school and high school subjects. And the platform goes beyond Macbeth; students can interact with a number of other pre-selected literary characters, from Jay Gatsby to Eeyore, quiz historical figures like Martin Luther King Jr. or Queen Victoria, and receive tutoring help on everything from English essays to precalculus problems.
After the Executive Council approved a $2.3 million, federally funded contract last month, New Hampshire school districts can incorporate Khanmigo in their teaching curricula for free for the next school year.
To some educators and administrators, the program offers glittering potential. Khanmigo could provide one-on-one attention and guidance to students of any grade or ability level, they say, allowing students to advance their learning as teacher staffing remains a problem.
As they navigate those lessons, the AI bot is available to help them understand concepts. Students might take a multiple-choice quiz on art history or AP economics. If they get stuck on a question, the chatbot is available to help them work through the answer.
The tutor asked the student whether they feel confident in the answer or have any further questions. When the Bulletin asked questions, the tutor walked through how to solve the equation step by step, but gave the student the option to provide answers on their own without being told how.
