Question

Anyone can help w/ a line integral?

Answer 1

i can try :)

Answer 2

the suspense is killing me....

Answer 3

ok, Find the work done by the force field F(x,y)=xi+(y+2)j in moving an object along an arch of the cycloid, r(t)=(t-sin(t))i+(1-cos(t))j, where 0<=t<=2

Answer 4

sorry it took some time to type

Answer 5

and it's 0<=t<=2pi
sorry

Answer 6

ahhh..vectors with the i and the j and the stuff...... you tricked me :) sorry, but thats a little outta my league for the moment ;)

Answer 7

ok, but it's a problem in my line integrals section.
yeah, i hate vectors too

Answer 8

i just havent had the guts to look into vectors; I know they are just arrows pointing in directions....but for some reason I just havent got the nerve to tackle them yet :)

Answer 9

you took multivariate calculus right?
i'm surprised, my book went into vectors from the beginning

Answer 10

I have tried to read about multivariables, but at the moment I am still trying to grasp inegrating single variables...

Answer 11

or rather, dependant variables of the singular nature lol

Answer 12

oh. but you know about line integrals?
like integrate (y/x)ds where the curve is x=t^4 and y=t^4?

Answer 13

wait till you get to surface integrals, yo can someone show me how to do a non homogenous heat equation i skipped lectures and im lost

Answer 14

oh gosh

Answer 15

I know of:\[\int\limits_{}\sqrt{[f'(x)]^2 + [g'(x)]^2} dx\]

Answer 16

mathfool, i don't think anyone around has the knowlege to answer that
