Did anyone else find their first year boring in their math undergrad?

I decided to major in math because of all those cool mind blowing videos about math on youtube and because I thought I was pretty good at it, but a month and a half in, it just feels so repetitive. Implicit differentiation is literally just a bunch of algebra and linear algebra is just doing a bunch of arithmetic with matrices (even though that can be fun sometimes). The only course I really enjoy is my “intro to real anaylsis” which is a course that’s designed to make your life much easier when you get to real anaylsis in second or third year, and I like that course because it actually explains a lot of concepts of math that I didn’t really understand before.

I looked through the courses I would take throughout my undergrad and found out that the cool math courses don’t start until around third year, so right now I feel like I’m just gonna be bored until then. Did anyone else feel this way in their first couple years?

Undergraduate taking Graduate classes?

Not sure if this kind of post goes here, but I’m not sure where else to post.

I’m a freshman going to a top 30 school, and I’m majoring in Math and Physics. This year, I will finish multivariable calculus, discrete math, linear algebra, and ODE. I am taking the standard physics route, but I seem to be a few years ahead mathematically of what they’re teaching. I am interested in taking graduate-level courses for either math or physics by my sophomore or junior year (mostly introductory-level graduate courses, e.g., Graduate Topology 1 vs Undergraduate Topology 1).

Are there any recommendations for accelerating myself? How can I make my case to the department that I am able to assume such an intense load so early? I’m prepared to work very hard.

N Pendulum formula?

Hi guys, I’m not a mathematician, just a regular folk with average knowledge of math. I’m a web designer, and was trying to do a double pendulum in Javascript. It was quite easy since the formula for simulating one it can easily be found online. However, when trying to do a triple or quadruple pendulum, I figured out you can’t just copy/paste the formula for finding the position of the second point, since adding a third or fourth point would affect how point 1 and 2 move.

As I said, I have pretty average knowledge of math and don’t know how it would affect a third point the other two. Do any of you have any information of where I can find n pendulums formulas that I could use? or some insights of what extra information is involved whenever a point is added to an N pendulum.

Advanced math in simple words

Hi r/Math,

It’s difficult to explain (in a sense of telling rather than teaching) advanced math to children or even some adults. However if you are really good at Maths you almost always can find a way. The problem is I’m not. That’s why I am asking if you can give me some elegant and simple examples from any part/field of math like mine written below (obviously I’m not the author, just heard it somewhere)

Th. Let G and H be groups, and let φ: G → H be a homomorphism. Then then image of φ is isomorphic to the quotient group G / ker(φ).

Quaternions/Octonions, difference in answers purely by sign?

I’ve seen a bit on Quaternions and Octonions and how they lose the commutative and associative properties, but it is implied that the difference in the answer is purely a change in sign. Is that truly the case?

I’m particularly curious about this as I’m making my own system of mathematics and one key difference is that in my system, sign is purely context and handled separately from calculating magnitude.

With my undergraduate mathematics and statistics degree, I finally got my first job out of college!

I recently got hired for a Data Analyst position at a local financial company in my area. According to the job description, I’d mainly be taking in data and making visualizations using R and maybe some Python. I’d mainly be using Tableau but I’ve also been teaching myself MATLAB as well. I actually hated it in my undergrad, especially for my Calc 3 and Mathematical Statistics classes lol.

I’m hoping to work here for a bit and go after my Master’s in either Data Science or something similar. The only thing I’m really worried about with this job is using SQL. I have a basic understanding of it but I think I’m going to have to expand on my skills when I start this week.

I just felt like sharing the news and hope whoever reads this has a great day/evening :).

Stefan Boltzmann Equation (Non-stem major)

I’m trying to wrap my mind around this equation and have just about figured out how most of it works. However there is one thing left that I don’t understand. The denominator is 5.67 x 10^-8 w/m^-2 K^-4. The w/m^-2 cancel out with the top part of the equation but I don’t understand what factor the kelvin to -4 is. What does K^-4 work into the equation
