Merry Christmas!

Yeah, well, can any of you do this?

 

Find all differentiable functions sr0zPiG.gif such that

YXbfCEd.gif

For all real numbers x and all positive integers n.

That’s easy.

 

I had moar fun with Vector fields… all those quadric surfaces and area integrals <3

That’s easy.

Sure it is. But I’m not seeing an answer :smiley:

Ew, integrals

I wont get dat from me, that stuff was on last sem… I’m already done with it, not goin back.

I used to be able to do this. But then I started learning useful things for my later job…

shhhh let me pretend I’m good at undergrad

Haha XD Undergrad engineering stuff is the most useless waste of time ever (first and second year anyway) third year starts to get interesting with projects and things. That’s when you realise that a computer can do in two seconds everything that you struggled to learn for two years. Also that being good at maths does not guarantee you a job later on… It’s more about experience, appliable skills, CV and interview techniques.

 

But hey, you have to do it all to get that nice shiny certificate saying that you are a good engineer (which you might not be at all, whether you have it or not…) So let’s just follow the system like good sheep!!

Baaaaaa!

Amateurs… This is what I can accomplish:

oh god, biology, get that away from me!

Well, environmental engineering, but close enough

That diagram makes literally no sense. What is that, an artificial leaf?

A program called STELLA I use… You can create diagrams to calculate inputs/outputs in any system. For this one, it runs relationships of CO2 input, soil water input, heat energy input/output, changes in ambient temperature, water vapor output, and calorie content output for a leaf of a tree or plant. You simply change different variables or inputs to change the type of tree or weather conditions, etc.

 

So in layman’s terms, I use it to calculate the energy efficiency of a tree leaf

 

That’s the most complex one I use, most others are far simpler, and mostly relating to changes in storage of water systems (rivers, canals, or reservoirs).

Sounds like a rather oversimplified version of how an ecosystem works - is this theoretical or applied?

 

EDIT: Also I stuck your problem in Wolfram Alpha, Statue. It’s still trying to figure it out…

It can be either. I could use it to find the ultimate “superleaf” if I wanted. But currently I’m using it to find the efficiencies of different plant types along a riverbank.

 

Also, it’s only one small piece of an ecosystem

Figures. If you want a superleaf, here’s something to get you started on:

It’s neither: it’s magic

isn’t symbolab better?
