I am supposed to find the line integral over C of (x+y)ds where C is the line segment from (0,1,1) to (3,2,2)?
So far I have 3ti + (1+t)j + (1+t)k as the parameterisation of C, and when I make an integral from that, I get 3(sqrt(11)). But I am uncertain of this answer, so if anyone could help confirm that (or even just the parameterisation), that would be very helpful. Thank you!
