Is the Line Integral Independent of the Path?

Click For Summary
SUMMARY

The line integral \(\int_{C} (y^2 - 3x^2)dx + (2xy + 2)dy\) is evaluated over a smooth curve \(C\) from the point (0,1) to (1,3). The discussion confirms that the integral is independent of the path, allowing for the selection of a straightforward path, such as a straight line, to simplify calculations. This conclusion is based on the properties of conservative vector fields, which dictate that the integral's value remains constant regardless of the chosen path between two points.

Homework Statement



Evalutate [itex]\int_{C}[/itex] (y2-3x2)dx + (2xy+2)dy, where C is a smooth curve from (0,1) to (1,3).

2. The attempt at a solution

I've checked through my notes and text but can't find an example. I'd appreciate it if someone could help me get this started.

The problem seems to imply that the integral is independent of the path. Is this true in general, or is this some special case?

If the integral is indeed independent of the path, then one way of solving the problem is to just pick an arbitrary smooth path and calculate the integral. A straight line is probably the easiest.
