Area line integral Show that the value of
xy² dx + (x²y + 2x) dy
depends only on the area of the region enclosed by C.
Transcribed Image Text:Area line integral Show that the value of xy² dx + (x²y + 2x) dy depends only on the area of the region enclosed by C.
Expert Solution
Step 1

We know that the area bounded by the curves is evaluated using the double integral formula which

is  RdA, where R is the region of integration.

We can write the given integral  xy2dx+x2y+2xdy= Mdx+Ndy, where M and N are the

components of a vector field such that M=xy2 and N=x2y+2x.
