Question

evaluate the line integral along the curve C

Answer 1

\[\int\limits_{?}^{C}(y+z) ds, C is the straight-line segment x=0 y=3-t, z=t from (0,3,0) \to (0,0,3)\]

Answer 2

if f(x) = C
and a and b are two numbers on the x-axis with a < b
then the integral (area under the curve) is given as
\[\int\limits_{a}^{b}f(x)dx\]
where dx is a small change in x

Answer 3

sorry, I don't know what a line integral is.. opps. :)

Answer 4

i thought the line integral was
\[\int\limits_{a}^{b}\sqrt{1+f'(x)^{2}}dx\]

Answer 5

it is
