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.

Issues with a 1999 Ford Expedition 5.4 4X4

Hey y’all! So I had a bad day today. Was taking the truck to job training about 40 miles away from where I live. The truck made it just fine until about a half mile from where I needed to go, she died. It was on a very slight grade uphill, and the cars speed started dropping suddenly. When I pressed my foot to the floor, nothing happened, and the tach kept dropping. By the time I pulled to the side of the road, it’s RPMs were way below idle (300ish instead of 750) and I turned her off.

All gauges read normal, so I tried starting her up again. Just the cranking and turning over sound, but the car wouldn’t get up to idle, it’d just sputter and I’d turn it off before it died. I thought I maybe ran out of fuel and my car hadn’t let me know, so a kind stranger took me to get a gas can and we came back around 20 minutes later. Put new gas in and car started perfect, so stranger drove off.

After about a minute, the car began doing what it did before, with shuddering and falling RPMs before I turned it off. I waited for the tow guy to arrive, and he managed to start the car (albiet roughly) and get it into the flatbed. We drove the 40 miles back to my house and it started right up to get it off the flatbed. Turned it off and when I attempted to restart the motor, just sputtering and nothing else.

I did some thinking and came to the conclusion that the fuel filter is clogged. My thinking is this, no check engine light or codes, and the Mass Air Flow sensor is brand new, so doubtfully an intake issue. The Triton engines have individual coils and sparkplugs, and there were no signs of misfire before the car died, and even then, misfires make that car run like crap, but they don’t really kill it (I’ve dealt with them before). Not to mention the battery is healthy and the alternator is new, so I don’t think ignition is our issue.

Finally, I come to fuel. The car starts up for a little after sitting, so I think that crap gets lodged in the filter as it’s running and chokes the engine out.

But I’m only a 17 year old kid, so I don’t really know if my line of thinking is correct, so I need your help car guys of Reddit! I have a new job and cannot afford to be out for awhile, so I’m trying to diagnose and fix the issue as soon as possible.

Thanks for reading y’all!

Car Salesman Treat Me Differently the 2nd I Come in

I don’t know if this is where I should be posting this but I have noticed this on two separate occasions. I (F) went into a honda dealership with my with mother and the salesman was rude, unconcerned, and just overall unpleasant. However, we liked the car so when we came into sign the papers he completely changed his attitude. He was pleasant, making jokes and really helpful. When I went in to an Acura dealer with my mother again to buy a used Kia Optima the same thing occurred. I just want to know if any one else has experienced this because i’ve asked and most people say that they’re pleasant throughout the whole process.

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.
