d/dx of x^n = nx^(n-1) : Solves for slope of fcn at all pts

integral of x^n = x^(n+1)/n+1 + constant : Solves for area under fcn between pts

Boom literally all of calc 1 complete

ME here....
Sorry EE fags

But I just wanted to say, the EE dept at my uni is full of tenured prof. who just fail the shit out of every class so it comes as no suprise that it would take >4 years to get a 4 year degree.

I actually don't know any EE who have not had a w on their transcript because they flatout failed a class.

Meanwhile, ME dept turns a blind eye to 90% of the cheating that goes on. It's no wonder ME kids get laughed at, and ones who graduate with high 3's still don't know what the fuck they are doing.

Goodluck, I know your shit isn't easy.


If anyone reads this, can I get some advice on pursuing a graduate degree? Like how should I choose my school/pathway. What benefits does it have aside from "make money". I want to work in research and development. Maybe I should work on perfecting my maths?

I don't know :(

What is the best order to learn mathematics?

Is the order typically taught in elementary, middle, and high school, then college, the best order? Or is there an optimal order if we were to restart from scratch AND completely ignore practical applications?

That is, if the end goal were absolute knowledge of mathematics, not usefulness, what would be the best order to learn it all?

i think polarization of EM waves is easiest to understand when radio waves are used to help visualize it. Forget for a moment the orthogonal relationship between the electric field and the magnetic and just think of one field at a time, the electric and...
Lets suppose you and I wish to communicate via radio. We pick our frequency at 10m wavelength and set up our antenae but wait a moment, do we want antenna that stand up like a flag pole (vertical) or reach side to side like a clothesline? Intuition tells us that we'd probably better use the same type and intuition is right because the waves are polarized and the sending and receiving antenna polarization needs to match for best performance. Now imagine that there is a very tall conductive metal picket fence between you and I. It is 1000m high and the gaps between panels is 1m. Intuition tells us that our waves from the flagpole like vertical antenna will pass thru the gaps while the waves from a clothesline like horizontal antenna won't and again intuition is correct. If the wavelength is too long to fit thru the gap most of it won't go. The tall skinny gaps in the metal picket fence will easily let our vertical waves thru but in order for them to get thru with horizontal polarization they'd have to be less than 1m and ours aren't, so the horizontal polarization is '''filtered''' out by this physical obstruction.

I hope that helped

Psychology is a human science.

That means it still has foundations on logic propositions, math (altough statistics and probabilistics only) and it studies patterns related to humans, and the theories are all variable on the time parameter, like other human sciences.


You are thinking of psychoanalysis, that's bullshit pseudo-science, OP.

Pic unrelated.

Don't think about it
Go to the gun store.
Buy the gun.

You will know what to do from there.

The shadow people wouldn't stalk you any more.

Have some fun. Buy the gun.

not a proof but

Fun fact of the day:

Light is an oscillating electric and magnetic field

Anyone have experience with WileyPlus?

I have the ability to purchase an access code for my textbook directly from the site, OR I could get a much cheaper access code from a third party. I'm just not sure if the access code needs to be connected to the book somehow.

Anyone else do this before?
