you the man data!

no it does not, so its from 0<t<(pi)

thanks trance, i actually figured that out a few hours after i made that post. i guess i am having trouble finding the limits to integrate from. I believe they are from 0 < t < 3(pi), but i am not sure.

With this problem, assuming i worked it correctly, i got the values for the parameticize. I am confused about what values to plug into x,y, and z. either what i just solved or the other values for x,y, and z. x = 2cost, y = 2sint, and z = 3t. r(t)=(1-t)<2,0,0> + t<-2,0,3(pi)>...

i don't believe so unless its known by another name?

Greetings again, Show that for F(x,y)=<2xy-3, x^(2)+4y^(3)+5> the line integral F(x,y).dr is independant of path. Then evaluate the line integral for any curve C with initial point (-1,2) and the terminal point (2,3). Thanks again, you all have been very helpful.

Greetings All Again, I wanted to thank you for the reply on my other problem, it was indeed very helpful and this is a very strange problem. So here goes : Compute the work done by the force field F(x,y,z) = <4y,2xz,3y> acting on an object as it moves along the helix defined...

Greetings All, I need serious help with this problem , well maybe several problems but I'll take it one at a time: Compute the line integral of (4xz + 2y)dx where C is the line segment from (2,1,0) to (4,0,2). Thanks

Greetings all, I need help setting up this problem: Use a double integral to find the area of the region enclosed by the curve r=4+3 cos (theta) Thanks

Greetings all, Find the max and min values of f(x,y.z)=3x-y-3z subject to x+y-z=0, x^(2)+2z^(2)=1 can anybody help me get this problem started. thanks

Greetings all, here goes... The integral of (xe^(x))/((x+1)^(2)) Thanks

Hey folks, HERE GOES... :confused: the integral of (sin 3t)^5 cos t dt i believe you have to use u substitution but i am having trouble getting it set up correctly. Thanks for any input :smile:

Yes you will have to integrate.

I am senior in college and I will be graduating in May 2005. I am about to complete my undergrad in Engineering Physics but I decided that I wanted to go more into the I.T. field for grad school since I have decided that I don't think I want to do physics. I researched a field call...

Greetings, I wasn't sure if you still needed input on this post but I just came across it. I was in the same situation you are in a few years ago. I came to college and was studying electrical engineering and after I took my first physics class, my professor suggested that I look into...
