Hello everyone, I am new here, and I was wondering if someone could provide me with some advice on how I should approach this in a smart way.

I basically really need some bigtime advice on the math part of Physics (or in general). I didn't have anyone to really talk with or that'd be able to give me advice on it until I found this amazing forum, so thanks for that!

I am going to start with the context first if that is okay.. will try to keep it short :)

I started studying math 6-7 months ago, but with precalc and a bit of calc and then came calc 1 at university and so I essentially skipped geometry.

For high school.. in general, it is safe to assume that my Maths from high school is close to non-existent. (and that especially for geometry as I did not have math for that particular whole year)

Also for physics, I didn't get physics in high school (or any science really besides a bit of biology and some non-connecting pieces of chemistry)

For the record, I am 19.

now..

So what you apply in physics of math, do you (implicitly perhaps) use geometry in solving it or some kinda intuition developed there? Cause I really feel that I miss some kind of outside part if you know what I mean..

The biggest hurdle is that I keep questioning the geometry part which implies that I START to question all my accumulated math skills those last couple months. Like oh man shouldn't I also go over precalc again this and that. Headgames..

To ask more specific toward the action part as I can keep whining all day long but without action no change's bound to happen...

The approach I was thinking of was to just simply do great time management and fill it in with geometry learning in the meantime during the semester if that is needed and perhaps going over a good algebra book after that to really make sure the foundations are solid? Again if that is needed. And also catch up with the analytical thinking that Physics provides. (ohyeah I study engineering so.. intro physics this semester was basically more practical with no conceptual explanation at all (/almost non-existent) so the accumulated knowledge is kind of empty knowledge in a way) There was a weighing I needed to make I either go to the exam or make sure I use that time to self-study it right now and really understand it as 2nd semster ofcourse builds on it. I chose the latter.

would you perhaps recommended to approach it a different way?As for books..

What books would you recommend?

Geometry:

I found this book online as a pdf on this site, geometry and trigonometry for calculus. (I'd use it mostly geometry but in precalculs I kinda struggled a bit more, because I didn't have that geometry of the triangles so wouldn't hurt to take the trig part too.)

I bought it two days ago, but then canceled it as I thought it might be better to ask for advice on this.

Would this book suffice to catch up with high school geometry?

or should I really go through it in a 'rigorous' way instead catching up with something like f.e. a book like this

Calculus:

for calculus I bought myself this one from peter lax. I am not a fan of them colorbooks at all and it seems interesting how it is laid out. He starts with series and then moves onto derivatives.

I thought it'd be a good way to go over calc again as there are parts that we didn't do like extremums (minimam maxima) and stuff like that.

Physics:

This is the one I bought for physics.Thanks in advance! I'd really very much appreciate some advice.

And also Thank you, @Mister T and @kuruman for the help and telling me where to post this kind of question. ( also to those that helped with that said homework problem :) )

Edit: changed the wording a little bit.
