Table 1. Geometry of the cam. Point x (in.) | y (in.) 1 2.20 0.00 1.28 0.88 3 0.66 1.14 4 0.00 1.20 -0.60 1.04 6. -1.04 0.60 7 -1.20 0.00 e 1. Schematic of cam profile. If the cam follows a straight line profile from x=1.28 to x= 0.66, what is the value of y at x=1.10 using Newton's divided difference method of interpolation and a first order polynomial. If the cam follows a quadratic profile from x=2.20 to x=1.28 to x=0.66, what is the value of y at x=1.10 using Lagrange method of interpolation and a second order polynomial. Find the cam profile using all seven points in Table 1, Newton's divided difference method of interpolation and a sixth order polynomial. Find the cam profile using all seven points in Table 1, Least-Squares method of regression and a sixth order polynomial.
