What kind of a joke class lets you use a formula sheet?

You can derive everything you need from Newton's laws.

$\frac{\partial L}{\partial x_i}=\frac{\text{d}}{\text{d}t}\frac{\partial L}{\partial\dot{x}_i}$
there you go thats all you need LOL

Ones that aren't based on rote memorization. They make up for it by making the questions more difficult. Or at least that's what they do at my uni.

Write the Schrödinger equation on an index card. You'll still flunk the test, but ol' teach will know you're a top lad.

All of mine do, they just make the questions harder. Why on earth would you expect someone to memorize the equation for the second moment of area for a quadrant of a circle? Literally useless for anyone to memorize.

obviously write down the lagrangian for the whole system including all particles so friction is really just the interactions between the particles of the "Object" and the "table" or whatever

Fucking brainlets on sci can't even do a 10000000000 component lagrangian with 10000000000 coupling terms baka

You want 10 hour exams?
Nobody has time for that and my professors can't remember it either.
