This interactive approximates the work done by a 2d vector field F along a curve (oriented in the positive x direction).[br]Enter Fx=x-component and Fy=y-component of your vector field F in the input fields (Fx=P and Fy=Q).[br]Change xn=Number of x Steps and the endpoints xmin and xmax of your curve.[br]Change v=vectorScale (readability).[br]Enter a different function for the curve (as an explicit function in x),[br]-----[br]Additional changes can be made to yn=Number of y Steps as well as ymins and ymax and vh=VectorHead (readability).
