hat's the flux of the vector field F(x,y,z) = (e^-y) i - (y) j + (x sinz) k across σ with outward orientation where σ is the portion of the elliptic cylinder r(u,v) = (2cos v) i + (sin v) j + (u) k with 0 ≤ u ≤ 5, 0 ≤ v ≤ 2pi???? Hard Calculas
whats*
how did you go from factoring to this?
im doing both and this the question im being asked
youre doing algebra and multivariable calculus?
yes
this one is challenging :)
I know
do you know what a vector field is*
every point in the subset
ok lets see, whats the derivative of x^2
im trying to get an idea of what you know, then i can start from there
Ok then its 1/2
the derivative of x^2 is 2x
How is it 2x explain please
ok one moment. I'm wondering, how did you end up taking multivariable calculus and algebra at the same time? to do multivariable calculus you need algebra 2, then pre-calculus, then calculus 1,2, (well i guess you can skip pre-calc)
you can skip algebra 1, and go to algebra 2. algebra 2 covers algebra 1. or better yet , take college algebra , thats a good start
i did algebra 2 and pre calc and i did bussiness math too
you need to know derivatives (and integrals) to find the flux of a vector field
ok so the algebra is just a refresher
yes
ok, and is this an online class?
im going to work on your question, ill be back later . i have to read my calculus book ,
okay
are these multiple choice questions?
do you have the multiple choice answers (that will help me)
No this isnt multiple choice
aww, its going to be harder :)
im also watching khanacademy videos on this, so i think i will be able to answer it soon
Okay No worries Ill be here
is it an electromagnetics problem
No i dont think so
this question is too hard i quit
i'll come up with an answer later
to solve this first u need to learn how to double or triple integrate plus how to find the gradient of a vector ! and also must know about divergence theorem and Gauss's law for flux. so I guess u better to take a complete course of multivariable calculus. :)
I can recommend a book :University Calculus by George B. Thomas Which in my opinion is the best book for calculus of all time ! BTW I can give u the pdf version
Yeah can i have the pdf version thank you
@avrillavigne
I need ur email address for that ! I can't attach the file here. send me an email I will respond as soon as I can :padariam@gmail.com
