Please help with 3 and 4. 518 Guided Projects Guided Project 77: Planimeters and vector fields Topics and skills: Vector calculus, Stokes' Theorem The planimeter is an ingenious device that allows one to trace a closed curve in the plane and determine the area of the region R enclosed by the curve (Figure 1). For this reason, it is an example of an "integrator," a mechanical device that computes areas of regions bounded by curves. The original planimeter was invented...
