Calc 3

Solid D's on 3 of the 4 tests of the course. Did not study, did not do homework. Funny thing is, the other test I got an A+ on, only missed one question. I didn't actually use any Calc 3 on that test, I solved the problems using my knowledge of geometry instead.

Although Calc 2 is usually heralded as the "hardest" Calculus course, I saw the most trouble among my classmates in Calc 3. It seems early sophomore year is the time when actually difficult classes begin and this coupled with the general malaise period of the time leads to a lot of tired kids fucking up their GPA in there. It doesn't help that legitimately hard topics like Lagrange multipliers, triple integrals and polar coordinates are slipped in there to fuck up those just coasting through.

In terms of actual dropout rates, Calc 1 has to take the cake (biologists and business majors, probably).

Calc1 test today
Chapter 3 on Stewart 7th ED

Did well on using product rule quotient rule chain rule etc.
But did bad on related rates.

English is my second language, The proff put a problem there that i could not even do because I didnt understand the objects used in the problem.

Here is the problem just like it that i googled when i got home.

"A dinghy is pulled toward a dock by a rope from the bow through a ring of the dock 5 feet above the bow, as shown in the figure. The rope is hauled in at the rate of 2 ft/sec.

How fast is the boat approaching the dock when 10 ft of rope are
out?"

I had no idea what a "dinghy" was, nor "bow" in this context, therefore i could not set the problem up. I know its a right triangle, so I BS'd something 3 mins before i had to turn it in

Had back to back exams last week. First midterms of grad school. Real analysis and foundations of computational mathematics, I'm doing applied math.

The real analysis exam had 3 questions on it. We had to do 2. This was a 2 hour long exam. I got INSANELY lucky, one of the questions had been pulled directly from the homework in the book, one of the unassigned problems of course, and it just so happened I had done that problem the day before while studying. Not only that, the first time I did it I got it wrong, looked at it, realized it was wrong and decided fuckit, but during the exam I worked my way through it and finished it and I'm 99% sure I got it right.

So I don't know my score yet but it was definitely between a 50 and a 60 because I got absolutely nowhere on the other problem. I'm pretty sure it was just me, too, half the class left early and I talked to one of the other guys and he got a 100%.

On the bright side, just looked up my FCM score and I got an 83/110, class average is a 44 lel, only one person beat me and got a 100, pretty sure they cheated as half the class is chinks

>>6844391
nope. the first math class you take in college is the hardest. clearly you either started in calc 1 or 2. i just cannot see calc 1 being hard at all. but most people struggle in calc 2 because they take it first semester and arent used to the difficulty. i took calc 3 my first semester and it was hard as fuck just because i wasnt used to the difficulty of college classes and it is on a totally different level from high school. honestly, the subject matter for all three is really easy and if there were people who were good at math but somehow started out in college algebra, they probably wouldn't think any of the 3 was hard.

Speaking of which, could any of you tell me how to solve separable equations if it isn't just multiplied terms? as in, (e.g.)

>> No.6844464

im the guy you were replying to

the point i was making was that if you take AP calc and get credit for it and place out of taking calc 1 and/or calc 2, you will probably get raped by the first class you take because college level math is a huge step up from high school level and you are skipping calc 1 which is where the learning curve begins.

obviously if you retake a subject you already took it is going to be trivially easy, the difficulty level of the class doesnt really matter if you already know the material

>> No.6844472

Plagiarism scares the fuck out of me constantly. Whenever writing a paper, I need to reread my paper multiple times making sure everything is paraphrased just enough and all that needs to be cited perfectly HAS been cited.

I'm in AP Calc AB and fucked up on the last derivatives test because I transferred to this school recently and have had to play catchup with a shitty teacher that didn't help at all. What resource(s) can I use to learn derivatives n shit for calc AB during my break next week? Is Khan Academy the best way?

Either that or Pauls Online Math notes.
All in all, the hardest part about straight up derivatives is the algebra.
