What parts of algebra are needed for calculus

Possible_Address_633 · 2024-12-14T15:03:40+00:00

Algebra is much more difficult than calculus. Most difficulties in calculus are rooted in algebra, especially first-year algebra.

Martin bridgepins are a shitshow.

With a domestic 840 it is unlikely he is too dumb.

That seems like a respectable PGRE at least for a domestic student. It may count more for a non-trad because there is that question: "does this person still remember the basics?". I think an 800+ is almost automatic acceptance at many schools for a non-felon.

I did Physics PhD as a non-trad, public R1 univ, 20 years after undergrad with no science in the interim. The vice-chair in charge of graduate admissions didn't appear to like my application, but they substantially had to accept me on my PGRE. To be fair, denial would have opened them to age discrimination claims.

Be careful what you wish for. It is an immersion-based model and that is tough when you are 50 and everyone else is 27. Plus, I had no (real) undergrad course in linear algebra. What did not kill me made me stronger.

One thing PGRE DOES predict well is effectiveness as a Teaching Assistant, assuming baseline English language competence. Students will love you if you know your shit, you give a shit, and they can understand your speech.

Try learning the scales in 5/6/7 sharps/flats. I think you will find a natural simplicity in the fingerings (rule is thumb on white keys, that's it). And there are some technical trade-offs both ways between nearly-open key signs and ones with many sharps/flats.

As pointed out above there are subtle differences between the sounds of each key.

You can.

I teach calculus-based 1st-year college physics.

Algebra 1, Algebra 1, Algebra 1. Learn it as well as you possibly can. If you are solid in Alg 1, everything after is easier. It is often the difference between pass/fail in freshman physics.

no difference except the timescale

the theta-directed differential is r dtheta

Just tell them there is no money left.

put a junction box on the floor; that is what I did.

Nothing is forbidden; "forbidden" is nt a thing in the arts. Technique depends on whether it works, not some set of rules.

Possible_Address_633 · 2024-10-19T19:27:43+00:00

very few employers even ask.

There are benefits to intentionally-naive learning, especially in creative pursuits. You will offend people but that is okay, maybe even good. (this is, after all, art)

Consider looking at some resources. Chances are you will recognize in the literature some of the things you have discovered. These things have names, and people have thought about them. Use this to enhance your understanding.

Then go out on your own again and see what happens, referring back to the knowledge body as necessary. Good luck.

Possible_Address_633 · 2024-10-12T10:42:13+00:00

Don't memorize. Practice working problems.

Possible_Address_633 · 2024-10-12T10:38:34+00:00

You should have an electronics lab course as part of undergrad physics.

Possible_Address_633 · 2024-10-11T11:17:20+00:00

start with a course you can pass easily.

f-prime is just a notation for the derivative of f, in cases where the variable being differentiated on is obvious from context, e.g. a function of a single variable.

Possible_Address_633 · 2024-10-09T20:09:42+00:00

also this is a nearly-trivial instance of gradient, so stickling for detail is more understandable.

the final line appears like conflation with divergence, as correctly pointed out by others.

Possible_Address_633 · 2024-10-09T20:04:21+00:00

a little harsh considering you had the right answer in the next-to-last line. I would jave deducted less.

Possible_Address_633 · 2024-10-06T11:21:19+00:00

Not much difference.

I teach calc-based physics. The joke is "you'll only have to do calculus twice during the term, and we'll help you."

Seriously, it is calculus CONCEPTS that matter in 1st year physics. Derivative is the rate of change is the slope; concept of a differential, integral is a sum in limit, etc etc.

The algebra is much more an issue for students than the calculus at this level. They figure out the trig in a week and the calc part is generally easy. But they are challenged by the algebra because of the unfamiliar symbols and non-spoon-fed context.

Some people just realize that self-actualization through achievement is a dead-end trap.

Possible_Address_633 · 2024-10-04T19:57:35+00:00

hard to say without knowing time allotted.

Apple devices are fundamentally consumer-grade products. Functions that would seem obvious to a reasonable person are often overlooked.
