CHAPTER 3: FIRST FUNDAMENTAL FORM
Taking turns to pick are 2 point on 2 corresponding coordinates curves and . When small enough so projection of curved parallelogram on osculating plane of at approximately the area of parallelogram on the contact plane. The edges of parallelogram on the contact plane are so the area of parallelogram is:
