Thanks! That really helped. We have thermodynamics next year so I'll try not to make the same mistake again!

That's what it was! It all works now, thank you!

Homework Statement This is derivation 2 from chapter 8 of Goldstein: It has been previously noted that the total time derivative of a function of ## q_i## and ## t ## can be added to the Lagrangian without changing the equations of motion. What does such an addition do to the canonical momenta...

Hi, I'm only a first year undergrad (UK) and everyone has different tastes in textbooks but one thing with the Feynman Lectures is that they don't have any problems to do. There's a set of accompanying exercises you can purchase but I haven't read them so can't comment on how good they are...

You might find this interesting: http://ph.qmul.ac.uk/sites/default/files/Lagrange.pdf There’s also something similar near the beginning of Goldstein’s Classical Mechanics

'Div, grad, curl, and all that' introduces vector calculus informally in the context of electrostatics which could be useful if you don't know vector calculus yet.

Thanks! That looks really interesting

Thanks so much for taking to the time to respond, it was super helpful! Is it a good idea to learn calculus rigorously as part of an analysis course? We some really basic groups in school (definition of a group, Lagrange's theorem, Klein group etc). Are there specific types of groups that are...

I am currently a first year undergraduate student studying physics in the UK. I will have some time over the summer and was wondering what maths it would be useful to self study as I will have access to my university's lecture notes and problem sets for all of their maths courses. By the end of...

Thanks!
