I plan on getting a degree in either computer science or computer engineering, but the issue is I never took a trigonometry or a calculus course yet. What is a good way to understand those subjects?
This and conceptual understanding of Calculus, especially the proofs and applications.Work a lot of problems.
Pre-Calculus is not enough. Best to be to learn the sequence of courses (which also may have interruptions) Introductory Algebra, Intermediate Algebra. A separate Trigonometry course may also come after or some later time after Intermediate Algebra. A possible continuation of that Algebra series is either "College Algebra", or the combined course called "Pre-Calculus" which is College Algebra And Trigonometry.In another thread a few months ago you said that you were in a community college. Many four-year CS degree programs have prerequisites of at least calculus, and some require linear algebra and differential equations. Does your college offer a precalculus course? If so, take it, as well as the two-semester/three quarter calculus sequence. The precalc couse very likely covers at least some trig.
The nomenclature at different schools isn't consistent. Some precalc courses include trig and some don't. Some schools offer precalc I and II, where the latter typically includes trig. At the school where I am currently an adjunct instructor, the relevant classes are called Precalc I: College Algebra and Precalc II: Trig.Pre-Calculus is not enough.
At least your school gives a dedicated Trigonometry course. It then gives a separate College Algebra course, so your school offers TWO SEPARATE courses, instead of the (where many schools do) the combination College Algebra And Trigonometry (this often being called plainly, Pre-calculus).The nomenclature at different schools isn't consistent.

I think that's a key insight -- being able to appreciate the geometry of the situation, instead of merely doing some algebra without little or no understanding of what the equations represent.For example in College Algebra, solving systems of linear equations was pretty confusing until I asked a bunch of questions that led to the realization that you’re really just taking lines or planes and seeing where they intersect simultaneously.
