Question
1. Consider y-f(x)%3Dsin(3x)+x² over [0, 37/2]. (By hand but use a calculator)
a) Use the three nodes Xo-0, x1- 37/4, x2= 3n/2 to construct a quadratic int rpolation
polynomial P2(x) and compare P2(1) and f(1).
b) Use the three nodes xo-0, x1= 7/2, x2= T, X3= 3t/2 to construct a cubic in rpolation
polynomial P3(x) and compare P3(1) and f(1).
