By order, I mean the content that is usually covered i.e. what methods are used, mathematical background topics like the dirac delta function or the Fourier transform etc.

TL;DR Summary: I am taking a math methods course this semester of which a large part are PDEs. I don't understand the context behind the order in which we are solving PDEs. I am interested in learning how other people were taught PDEs and any book recommendations you might have. I am taking a...

That is what I though. I forgot to include that. It should be: $$y(x,t) = y_{max} sin(kx+\omega t + \phi)$$

I understood that y(0,t)=0 at t =0 (from the homework statement)is the same as y(0,0)=0

Using the equation above I know that I have to find parameters k ##\omega## and ##\phi##. $$k = \frac{2\pi}{\lambda}$$ and $$\omega = 2\pi f$$ The problem I've been having is how you would go about finding ##\phi## since by solving: $$y(0,0)=0 \rightarrow sin(\phi)=0 \rightarrow \phi = 0...

I think I do. To summarise, if the object were free, it would only move in the y direction so not in the aforementioned path and if it were constrained to that path, we wouldn't be able to find the velocity since we can't calculate the other forces' work in order to apply the work-energy theorem.

This problem came from a past exam paper from my university's physics department. The exact wording is: Point-like object at O(0,0) is at rest and starts moving, without experiencing any friction, along the curve y = 2x^2-4x until it reaches point A(3 m, 6 m). The force applied to the object is...

I may have been unclear. It starts at (0,0) being at rest and then the F is applied to the object.

I have been trying to solve the following problem: Point-like object at (0,0) starts moving from rest along the path y = 2x2-4x until point A(3,6). This formula gives the total force applied on the object: F = 10xy i + 15 j. a) Find the work done by F along the path, b) Find the speed of the...

I did not make that clear. Yes, I have taken several physics courses in high school, including 1D mechanics, rigid body mechanics, electricity, circuits, optics, collisions, thermodynamics and I am currently studying electromagnetism.

I am living in Greece. We do not have science fairs, but I embark on maths and physics projects through the school clubs of which I am part. About your first remark, what I am trying to do is self-study maths, in order to be able to study the topics we cover at school, more rigorously. Greece's...

I am currently in the last year of my high school studies, and I wonder how to best prepare for university. I already have a solid coding base, having currently enrolled in a Python for physics course. I also am studying further maths, something like Calculus 2 in the US. How do you believe a...

I was thinking of starting a programming language of that sort, so thanks for the suggestion.

I was not sure of how to tie the physics with the programming together. I started glowscript and found it being much more enjoyable than simply learning coding skills. I found a great course on it...

I already have a good grasp of python programming and coding fundementals. I am looking to better expand skills in things like data analysis and visualisation. Also was thinking of starting R.
