- legit stupid question trigger warning -
Physics exam coming up later today and I haven't studied as well as I should have by far; I'm pretty sure I'll have to repeat it in a month. Still, for the sake of the attempt, what should I absolutely write down in my formula sheet (we can have a sheet of paper with anything handwritten on it) to give me a (negligible) chance to wing it? Subjects are electrostatics-/dynamics, (electro-)magnetism, optics, pretty much. As for the Physics, if you would help me, I'm mostly just asking for the most obvious shit just in case I'd miss it somehow.
However, my mathematical fundamentals (area/volume integrals, dealing with spherical coordinates, some substitution stuff, etc.) are still very lacking as well. Since I won't have time to make a super comprehensive formula sheet anyway, what should I write in baby steps when it comes to mathematical operations (as in shit I'll have to be able to use)?

My sincerest thanks for any help (even if it probably won't amount to anything).
