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.
