I used wikipedia to make my cheat sheet.

>>5981744
and added graphs from wikipedia to this side

>>5981744
I used wikipedia to study for my phd qualifiers =P

I'm still pissed about the error I fixed on the von neumann stability page that some know-nothing asshole reverted.

>>5981744
make any maths sheets?

>>5981833
I think I gave up halfway through the class because I was trying to figure out those crazy integrals

I don't think I did well in this class. Prof put me to sleep

>>5981833
Economics is math right?

>>5981852
hmmm... I sent this to two of my friends and neither told me about the title
Economic Analysis of Capital Investments

Gentlemen, I would be very grateful, if you uploaded an infographic concerning logarithms. I skipped school, when they were learning this subject and used some book to write down basic identities, but now that copybook is gone, and I just want to always have a quick and convenient piece of information available. Picrel is the ideal analogue of what I want. Also would be nice of you to mention some decent problem book on the subject, just to "feel" it, if you know what I mean.

Awesome job, guys. Really, great infographics.

Now can someone do the same thing except with HEAT ENGINE CYCLES.

Also, infographic thread I guess

>>5981744

there's a lot of mistakes in this

>>5982563

To mention a few, steady doesn't mean d/dt = 0, but rather partial derivative w.r.t. time = 0, because even if a thermodynamic property doesnt change with time, it can change from point to point of the control volume. Also for polytropic process, pV^n equals a constant, not 0

bumping with infographics. I know there's one with heat engine cycles out there.

I'm going to keep bumping this thread until someone responds with a good textbook/website reference on thermodynamic heat engine cycles.

The past two books I've gotten have been shit (Moran and Borgnakke), and googling it has turned up shit.

Bumping with infographics

>>5982583
think i wrote that part before taking multivariate
tell me all the mistakes you see so i can correct them

God damn it.

>>5982535
there's heat engine cycles on
>>5981751
also wikipedia is really good at this
do i have to link each article or can you find it?

>>5983089
There's ideal efficiency/carnot equations. I'm talking about T/S P/V diagrams and energy/enthalpy/entropy calculation equations.

Do you have sums and products properties sheets? Those with sigma and pi notations I mean.

I always tell my students to never trust what their classmates write.

FUCKING WIKIPEDIA
srsly just fucking draw it on a piece of paper from wikipedia
>>5983524
nope I studied engineering mostly

Okay, so I found this one, but aside from that there is nothing more on ecalc.com.
Would anyone bother to upload a math sheet with some basic combinatorics going?

Wikipedia doesn't even remotely have what I'm looking for. It has T/S diagrams, and MAYBE P/V diagrams, but all of them are too fucking simplified. I'm looking for the fucking math and derivations of this shit.

RECOMMEND ME A TEXTBOOK. I BOUGHT ONE AND PIRATED ANOTHER AND THEY BOTH SUCK.

>>5983666
I don't go to you school, so your course number is meaningless to me.
