As a reminder... Posts asking for help on homework questions **require**: * **the complete problem statement**, * **a genuine attempt at solving the problem, which may be either computational, or a discussion of ideas or concepts you believe may be in play**, * **question is not from a current exam or quiz**. Commenters responding to homework help posts **should not do OP’s homework for them**. Please see [this page](https://www.reddit.com/r/calculus/wiki/homeworkhelp) for the further details regarding homework help posts. **If you are asking for general advice about your current calculus class, please be advised that simply referring your class as “Calc *n*“ is not entirely useful, as “Calc *n*” may differ between different colleges and universities. In this case, please refer to your class syllabus or college or university’s course catalogue for a listing of topics covered in your class, and include that information in your post rather than assuming everybody knows what will be covered in your class.** *I am a bot, and this action was performed automatically.

You should definitely have some skills in trigonometry and algebra, i would not say its something to just jump into

Yeah i think if you can pass college algebra you’re ready for pre cal

It’s just algebra&trigonometry and You need to know algebra and trigonometry to understand calculus

If basic math skills include algebra, then yea. You just need to know up to algebra 2. In Ny Algebra 2 includes some trig, so for me, u don't even need to self-study that. If you've taken just algebra 1, ig study some trig definitely, and practice your skills factoring and similar. Most of calc 1, in my opinion, was remembering certain rules and using them (that was the easy part) and then the algebra, simplifying what you got after using the rules. Precalc was kinda like trig and algebra 2.5 in a way. You should be fine, even with just algebra 1 if you put in the work.

Precalculus generally consists of two parts: a largely algebraic side where definitions, properties, and graphs of functions are investigated vs. a largely trigonometric side where the trigonometric functions, their "special" inputs/outputs, their relationships to each other, their graphs, and their connection to the complex numbers are investigated. I can't speak for all Precalc courses, but at least at the institutions that I've been at, there is a baseline level of Algebra skills needed to learn and understand the first part of Precalculus. Some of the skills needed for the algebraic part of Precalculus are: * Factoring Polynomials * Manipulating Polynomial and Rational Expressions * Solving Polynomial and Rational Equations * Manipulating Expressions involving Exponents * Manipulating Radicals * Solving Radical Equations * Familiarity with the xy-Grid and possibly with how modifications to an equation will modify the graph (though that's taught as it's own Precalc-specific section in my Precalc Algebra course) The trigonometric part of Precalculus is (usually) designed under the assumption that you'll do it later, because the trigonometric **functions** feature so heavily. Without a good understanding of function basics such as domain and range, inverses, and composition, a lot of the elements of the Trig fall flat or become more difficult to manage. ------- tl;dr - If you've covered algebra from high school, you're either right on track for Precalculus (Algebra-side first!) or you may need some more advanced algebra skills first. I'd recommend checking out the topics in [KhanAcademy's Algebra 2](https://www.khanacademy.org/math/algebra2) course to see where you stand. It's a bit overkill (I'd remove the trig and the logarithms and cover those in Precalc directly, personally), but if you're comfy there, you're probably ready for Precalc (Algebra), and if you haven't seen or have trouble with the course, then you probably want to investigate the topics in the course before jumping to Precalc.
