With differentiation, one of the major concepts of calculus. Integration involves the calculation of an integral, which is useful to find many quantities such as areas, volumes, and displacement.
Evaluate the line integral -ydx + xdy along the curve
C : y = 3x from (3, 3) to (0,0).
NOTE: Enter the exact answer.
-ydx + xdy
Let C be the closed, piecewise smooth curve formed by traveling in straight lines between the points (−4, 2), (−4, −3), (2, −2), (2, 7), and back to (-4, 2), in that order. Use Green's theorem to evaluate the
following integral.
