what is line integral - for example if I can draw graph of parabola and i can calculate the area under the graph. But how can i measure the length of parabolic path.

ds=√(dx

To get the arc length between 2 values of x, integrate ds between those values.

A line integral is more complex idea than the area under a curve in 2 dimensions.

It is done in 3 dimensions [or more]

The arc length is an application of integration in 2 D and the formula was given to yoou in the previous post.
