I'm failing my calculus III class bros

Just reading calculus it gives me anxiety. The problem is not the subject but the fucking exam with no time to do everything

>studying STEM
your own fault
t. humanities brainlet

But I want good job. Only other option is healthcare

Multivariate calculus is easy

These were the """easy""" problems. God I hate being a brainlet

Did you find the solution? I'm curious, it's been a while since i've studied calculus. Do you need to use the jacobian matrix or something like that?

easy, mate.
convert to polar coordinates, integrate over radius and angle and divide result by 5

Those are easy tbf, you just need to integrate in function of x considering y as a constant and then in funtion of y (and vice-versa for item b).

this is basic shit, mate, literally just integrate the stuff; you can switch order of integration because of fubini's theorem, I think

not being rude btu that is not hard
Taking a as an example:
dx is on the left so you differentiate with respect to x first and then put in 2 and 0 for both x terms
then do it again in terms of y and put in 1 and -1.

We did this in Year 2 Engineering Maths class.
It's really not bad lad.
If you know integration it's just doing the same rules over again except twice.
COME ON.

I did this literally on the first semester of university, but I was in physics

solving it for OP once won't help, he said he's failing.

>differentiate
integrate****

GOOD GOLLY I AM A GIDDY GOAT
I MEANT INTEGRATE

I don't agree. Sometimes you are blocked because you don't know how to "read" the problems, and seeing some solutions helps you unblock that, and afterwards it's just practicing.

I don't know how it works in other countries but Year 1 of British university is the easiest thing ever.
People spend it drinking 24/7 and as long as you just pass all your exams you get to go onto the next year with your Year 1 results not affecting your overall degree grade at all.
It's Year 2 onwards where things start to matter.

Year 1 was basically another year of high school desu

Solution using r = sin(3 theta)

I can solve them with enough time and referencing of my notes, but it takes me very long and I constantly make many mistakes along the way.

I did physics in the hardest department in the country, so my experience is definitely not representative of the country, but:
First year you get immediately hit with a ton of shit you never learned but you are expected to know beforehand, so almost half of the people drop out of the programme during the first year.
Afterwards, every year going forward is a step up in difficulty, and in the last year people are literally going crazy.

I hear in engineering it's hard during the first two years and afterwards it's easy. In Physics and Maths i'ts exponential difficulty, and the professors have a joke saying that it's the factorial year (students take 1 year to pass "year 1", 2 years to pass "year 2" and 3 years to pass "year 3", so 6 years total) this for the average/below average students. The bad students just drop out.

Maths for me was just seeing how it's figured out and doing it over and over and over again.
It's literally monkey see monkey do at that point. You're doing the same shit with different numbers.

As long as your lecturer doesn't start asking the questions in official Maths language as my guy did in Year 3 - it should be smooth sailing if you just copy that monkey see monkey do structure.
Doing it once is insufficient though try doing multiple variations of the same "type" of question - ie multiple integrals as one example. Then it will really sink into your mind no matter what your IQ is.

I had the same problem when I was in uni; just do it more and you will gain automatisms.

that sounds fucking horrible
I guess because we pay £9250 a year they're nicer to us in Year 1.

For me Year 1 = Easy, Year 2 = Harder but still not bad, Year 3 = Quite difficult but all my exams have been cancelled due to Corona. I'm starting my Masters in September.

That's a myth about engineering going easier after the first 2 years. Generally people are more used to study and know how to get good notes, etc but it's not easier at least in my degree

It was a fucking nightmare, but when we finished we felt like we had gone through war and survived. Everyone else hates physics students because we are very arrogant towards other courser because of this mentality (we survived through hell and you did not).

Tuition here is €800/year, so people don't really care if they fail an year or two. Also, I did my MSc at UCL, and I paid £20k, it was a lot more than that.

I lived with a Physics student in Year 1.
At the start of the year he looked like a chad and at the end of it he looked like a dirty incel.
Even the medicine girl I lived with worked less hours than he did.
Wouldn't want to touch Physics in a million years.

What job did you end up getting out of it? Was it worth all the pain?

haven't checked my courses since they got moved online and at this point I'm too afraid to

just the feedback I heard from friends; but that also means that your studying skills grow faster than the difficulty, which idn't happen in my course

This You just need to to enough exercises so that the ones in the exam are similar to something you've already done before and you just auto-pilot it.
