AI Thread Summary
Choosing precalculus over college algebra and trigonometry can be a strategic decision based on time constraints. The course content can vary significantly between institutions, with some covering topics like Probability/Statistics while others may exclude Sequences/Series. It's advisable to consult the course catalog or the instructor's webpage for specific details about the syllabus and topics to be covered. Generally, precalculus includes subjects such as equations, relations, functions, graphing, polynomial and rational functions, exponential and logarithmic functions, circular functions, coordinate geometry, analytic trigonometry, matrices, determinants, and the binomial theorem. Getting a head start on these topics can enhance preparedness for the class.

I decided to take precal instead of college algebra and trig in two different semesters. I made this choice because of a time issue. Class doesn't start for 2 weeks or so but I'm curious on what topics that will be presented. Also, what things should I get a head start on before starting the class.

It varies from school to school. Some courses will cover Probability/Stats while others won't, and some might omit Sequences/Series. It would be best to try and find resources at your institution so that you can make effective use of your time. But, in general, the topics covered are: Equations, relations, functions, graphing; polynomial, rational, exponential, logarithmic, and circular functions with applications; coordinate geometry of lines and conics; analytic trigonometry; matrices, determinants; binomial theorem.

Have you checked your course catalog? The description of the course will sometimes tell you what the class is going to cover. You can also check to see if your instructor has a webpage; sometimes they will post a syllabus early.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
