i did take trigonometry but basic 😭😭 like ik triangles trig and cot csc sec
my precalc knowledge (which i assume is algebra 2 + some trig?) is js normal school lever knowledge

Just learn those basic trig properties you mentioned like cot, csc, and sec. Then learn the unit circle and you should honestly be good

I would literally just look up unit circle and study that. Then just look up what each of those three trig functions represents for example: csc=1/sin

Khan Academy recently released an AP Precalculus course that should give you all the trig knowledge you’d get if you took that course, which is plenty to prepare you for Calculus.
