Thread: Line integral

Could use some help in evaluating this line integral....



where the path r is the line = x, from (1,1) to (4,2)

First you need to parameterize the curve

let then

Note: there are many other ways we have parameterized this.

Now we can compute dy and dx



now we just substitute in to the above and evalute



Now it is off to the races.

Good luck.
